How Much Mono Backing for Braid? Expert Tips

Fishing enthusiasts often encounter a unique dilemma when selecting the right fishing line for their reels. 

Two prominent options frequently under consideration are monofilament (mono) backing and braided (braid) fishing lines. 

Mono backing, short for monofilament backing, is the foundation upon which a braided fishing line is spooled.

Braid fishing lines, characterized by their exceptional strength and thin diameter, have gained popularity among anglers for various applications. 

They offer several advantages that make them suitable for various fishing scenarios. 

How Much Mono Backing for Braid

Determining the Right Amount of Mono Backing for Braid:

You can get away with 12 lb mono, But it would be better to use 8lb mono as the backing of your spinning reels. 

Mono as thick as you will have a problem. Braid can easily slip between more thick mono. 

And gets tangled because she tries to get off the spool. It leaves a thick mono big knot on your spool. 

Due to this, the line could be more balanced. And you should have 150 yards of braid, which is enough line to handle any Fish, whether you’re fishing on the beach. 

You must get the perfect Braid and Mono on your reel for the best fishing. What knot you use to tie Braid to Arbor does not matter. Keep your Spinning Reel on 150-100 yards Braid.

Tie backing to your braid to fill the rest of the spool with backing. Ensure you have the best line amount without too much Braid or Mono on your reel. 

Moving the line on the other Reel Will have the correct amount of mono backing in the top of the braid.

Understanding Mono Backing and Braid

What is Mono Backing?

Mono backing, short for monofilament backing, is the initial section of a fishing line spooled onto a reel before braided or other fishing lines are added.

 It typically consists of a monofilament line, a single strand of synthetic material, such as nylon, designed for fishing applications. 

Monofilament backing is made from a single strand of nylon or similar materials. It’s known for its flexibility, durability, and high knot strength.

Diameter: Mono backing is typically thicker in diameter compared to braided lines. 

This characteristic makes it an excellent choice for filling the bulk of the spool, especially when braided lines are thinner.

Stretch: Monofilament lines act as shock absorbers in playing a fish due to their stretch. 

This stretch can help prevent sudden line breakage during powerful strikes or aggressive runs by the fish.

Knot Compatibility: Mono backing is well-known for its knot-holding ability. It forms secure knots that ensure a strong connection between different fishing lines.

Why Combine Mono Backing and Braid

What is a Braid Fishing Line?

The braid fishing line, often called “braid,” stands out from other traditional options, such as monofilament and fluorocarbon lines, due to its unique characteristics.

 Braid is made from multiple synthetic fibres, typically woven to form a single, ultra-thin, incredibly strong fishing line. 

These synthetic fibers can comprise Spectra, Dyneema, or other high-strength polyethylene materials. 

The construction of these fibers is what gives the braid its distinct properties.

Characteristics Of Braid Fishing Line:

Strength: Braid fishing lines are known for their exceptional strength-to-diameter ratio. 

They are significantly stronger than monofilament lines of the same diameter, making them popular for anglers targeting larger and more powerful fish species.

Low Stretch: One of the hallmark features of braid is its minimal stretch. 

Braid has very little to no stretch, which means that when you set the hook or fight with a fish, there is virtually no give in the line. 

This low stretch provides excellent sensitivity, allowing anglers to feel even the subtlest bites.

Thin Diameter: The braid is much thinner than monofilament lines of similar strength. 

This thinness increases line capacity on fishing reels and improves casting distance.

Abrasion Resistance: Braid lines are highly resistant to abrasion and can withstand contact with rocks, snags, and other underwater obstacles.

 This durability makes them suitable for both freshwater and saltwater fishing.

Visibility: Braid lines are often highly visible due to their vibrant colors. While this can be an advantage for detecting line movement, it can also be a disadvantage in clear or heavily pressured fishing environments where fish may be line-shy.

Casting: Braid is popular for casting reels (spinning and baitcasting) due to its thin diameter, low stretch, and increased casting distance.

Vertical Jigging: Anglers often use braid for vertical jigging because it allows for better sensitivity when detecting strikes from below the boat.

Trolling: The braid’s strength and thin diameter make it a preferred choice for big-game fishing in trolling applications.

Topwater Fishing: Braid suits topwater lures, as its low stretch provides quick hook sets.

Why Combine Mono Backing and Braid?

The combination of monofilament (mono) backing and braided (braid) fishing lines on a reel is a strategic choice by many anglers, and it offers several advantages in different fishing scenarios. 

Here are some key reasons why anglers choose to combine mono backing and braid:

Line Capacity Management: Braided lines are thinner in diameter than monofilament lines of similar strength. 

This means you can spool a significant amount of braided line on your reel. However, many fishing reels, especially spinning reels, have a large spool diameter, and filling the entire spool with a braided line can be cost-prohibitive and unnecessary. 

By using mono backing, you can fill most of the spool with a less expensive monofilament line while retaining the benefits of a braided line when needed.

Preventing Slippage: Braided lines are known for their smooth and slick surface. This can lead to issues with line slippage on the reel spool, which can reduce casting distance and overall reel performance. 

With its textured surface, Mono backing prevents braided lines from slipping, ensuring they remain securely spooled.

Knot Compatibility: Braid and mono have different properties, including diameter and texture. 

Knots used to connect lines of different materials and diameters can be challenging to tie directly between braid and monofilament. 

Mono backing provides a solid base for tying knots that securely connect the two line types. 

Common knots for this purpose include the Arbor Knot or the Uni-to-Uni Knot.

Shock Absorption: Monofilament has some stretch, while braid is virtually non-stretch. 

This stretch in the mono backing can act as a shock absorber when you set the hook or play a fish, reducing the likelihood of sudden line breakage during powerful fish strikes or runs. This helps protect the braid from snapping and losing the fish.

Versatility: The combination of mono backing and braid provides versatility. Anglers can tailor their setups to specific fishing conditions and target species. They can use the advantages of braid, such as its strength and sensitivity, while also having the flexibility to switch to different types of monofilament lines if needed.

Cost-Effective Spooling: Braided lines can be more expensive than monofilament lines. 

By using mono backing, anglers can save money by reducing the braided line they need to purchase while maintaining the braided line’s benefits when required.

Combining mono backing and braid on your reel offers the best of both worlds.

 It allows you to maximize line capacity, prevent slippage, maintain knot security, and enjoy the advantages of both monofilament and braided lines, depending on the situation you encounter during your fishing adventures.

What are the Factors Affecting Mono Backing Length?

Several factors come into play when determining the appropriate length of mono backing for your fishing setup.

Reel Size and Capacity

The size and capacity of your fishing reel play a significant role in determining how much mono backing is required. Here’s how reel size influences the choice of mono backing:

Spool Diameter: Larger fishing reels, like those designed for big game or saltwater fishing, have spools with greater diameters. 

These larger spools can accommodate more fishing lines, both in length and diameter. 

You can spool more mono backing using a larger reel before attaching your main braided line. 

This extra capacity allows you to take full advantage of the benefits of braid, such as increased line strength and casting distance.

Line Capacity Markings: Many fishing reels have line capacity markings, which indicate the recommended amount of different line types (e.g., mono, braid, fluorocarbon) that can be spooled on the reel. 

These markings serve as a useful guide for anglers. Typically, filling about 1/3 to 1/2 of your reel spool with mono backing is recommended.

 Check your reel’s documentation or manufacturer’s website for these specifications.

Fishing Scenario: The choice of reel size should also be influenced by your specific fishing scenario. 

Different types of fishing, such as freshwater bass fishing, inshore saltwater fishing, or offshore deep-sea fishing, may require reels of varying sizes and capacities. 

Choosing the appropriate reel for your target species and fishing conditions is essential to ensure you have the right mono backing to support your braid.

Line-to-Species Compatibility: Consider the fish species you intend to target. Larger and more powerful species may require larger reels with increased line capacity. 

Smaller species may be adequately targeted with smaller reels. Matching the reel size to the target species helps ensure you have the right combination of mono backing and braid for your angling needs.

Target Species

Different fish species come in various sizes and exhibit varying behaviors and power. 

The choice of target species significantly affects the amount of mono backing required. Here’s how:

Size of Target Species: The size of the fish you intend to catch is a critical consideration. 

Larger and more powerful species, such as marlin, tuna, or trophy-sized bass, can make powerful runs and put immense stress on your fishing line. 

In such cases, having an adequate length of mono backing is essential. It allows you to absorb the initial shock and runs off the fish while still enjoying the benefits of braid once the fish is under control.

Deep-Sea Fishing: In deep-sea fishing scenarios, where you might target massive game fish like sharks or sailfish, the length of your mono backing becomes particularly important. 

These species can make prolonged, powerful runs, and having enough mono backing can prevent your braid from being stripped off the reel prematurely.

Inshore and Freshwater Species: When targeting smaller inshore or freshwater species like trout, bass, or panfish, you may not require as much mono backing. These fish generally do not make extreme long-distance runs, so a moderate amount of mono backing can suffice.

Fishing Technique

The specific fishing technique you plan to use also influences the choice of mono backing length. Different techniques have distinct requirements:

Trolling: Trolling involves trailing lures or bait behind a moving boat. It’s commonly used in offshore and big game fishing. 

When trolling, having ample mono backing is crucial, as it can help handle the stress of trolling large lures or battling powerful fish that may strike at a distance from the boat.

Casting: Casting techniques may not require as much mono backing, whether for freshwater bass or inshore saltwater species. 

However, having enough backing to handle the initial force when a fish strikes and takes off is essential.

Bottom Fishing: In bottom fishing or jigging techniques, where you often target fish dwelling near the ocean floor, you might not need extensive mono backing. Braid sensitivity and lack of stretch can be highly advantageous in these scenarios.

Fly Fishing: Fly fishing typically doesn’t involve mono backing because it uses a different setup, with a fly line, leader, and tippet.

What Benefits of Proper Mono Backing for Braid?

Combining mono backing and braid fishing lines offers several advantages in different fishing scenarios. 

Here, we’ll explore three key benefits of using proper mono backing for braid:

Improved Casting Performance

One of the significant benefits of using mono backing with braid is the enhancement of casting performance. 

Mono backing provides several advantages in this regard:

Casting Distance: The thicker diameter of mono backing fills the lower portion of the reel spool, allowing the braided line to be wound on top of it. 

This combination creates a “cushion” effect that aids in smoother and longer casts. The additional bulk and weight from the mono backing help load the rod more effectively, allowing for increased casting distance.

Reduced Wind Knots: Braided lines, especially when spooled directly on a reel, are prone to wind knots and tangles, hindering casting performance. 

Mono backing mitigates this issue by providing a stable base for the braid, reducing the risk of wind knots during casting.

Controlled Casting Force: Mono backing’s slight stretch can help absorb and distribute the force generated during a cast.

 This controlled casting force results in smoother and more accurate casts, particularly when using baitcasting and spinning reels.

Line Capacity and Versatility

Properly spooled mono backing enhances line capacity and versatility on your fishing reel:

Line Capacity: The combination of mono backing and braid allows you to maximize the line capacity of your reel.

 This is especially important when targeting larger or stronger fish species that may require extended line lengths. 

With more line capacity, you can play fish more effectively and have a better chance of landing your catch.

Versatility: The use of mono backing offers versatility in your fishing setup. You can adapt to various fishing scenarios by changing the type and length of the braided line you spool on top of the backing. 

This adaptability allows you to switch between different fishing techniques and target a wide range of species without the need for multiple reels.

Reducing Line Twist and Tangles

Mono backing helps reduce line twist and tangles, which are common issues associated with braided lines:

Reduced Line Twist: Braid has minimal stretch and can twist easily during retrieves, especially with lures and spinners. 

Adding mono backing with some stretch absorbs and minimizes line twists, resulting in smoother, more manageable line control.

Preventing Line Digging: Braided lines can dig into the spool under heavy tension on some reels, causing tangles and knots. 

Mono backing provides a buffer layer that prevents braided lines from digging into the spool, reducing the risk of line-related issues.

Improved Knot Performance: The textured surface of mono backing facilitates the formation of secure knots, not only between the backing and braid but also for attaching terminal tackle, leaders, or connectors. 

This ensures knot security and minimizes the risk of knot failures during fishing.

How to Spooling Mono Backing and Braid?

Spooling mono backing and braid onto your fishing reel is a crucial process ensuring optimal performance during fishing trips. Here’s a step-by-step guide to help you through the process:

Choosing the Right Knots

Before spooling, you must choose the right knots for securing your mono backing to your braided line. 

Here are some commonly used knots for this purpose:

Arbor Knot: This knot is used to attach your mono backing to the spool arbor of your reel. 

It provides a secure connection, preventing slippage.

Uni-to-Uni Knot: The Uni-to-Uni Knot is popular for connecting mono backing to a braided line. 

It creates a strong and reliable link between the two types of lines.

Spooling Process

Once you’ve selected the appropriate knots, you can proceed with spooling your mono backing and braid onto your reel:

Prepare Your Reel: Attach the mono backing to the spool arbor using the Arbor Knot. Make sure it’s secure, and leave a tag end of a few inches.

Wind the Mono Backing: Wind the mono backing onto the reel spool. Apply slight tension as you wind to ensure it’s evenly distributed and fills the lower portion of the spool. 

Continue spooling until you have the desired amount of mono backing.

Tie the Uni-to-Uni Knot: After spooling the mono backing, tie the Uni-to-Uni Knot to connect the braided line to the mono backing. 

This knot should be strong and secure to prevent line separation during casting and fighting fish.

Wind the Braid:

  1. Start spooling the braided line onto the reel.
  2. Again, apply tension to ensure an even distribution.
  3. Continue until you’ve filled the spool to the desired level.

Tighten Knots: After spooling both lines, carefully tighten the knots between the mono backing and the braided line. 

Trim any excess tag ends, leaving just a small amount to maintain knot integrity.

Testing and Adjusting

Once you’ve spooled the mono backing and braid, perform some tests and adjustments to ensure everything is in order:

Tension Test:

  1. Apply tension to the line with your hand and slowly reel it in.
  2. Check for any slipping or issues with the knots.
  3. If you detect problems, re-tie the knots and ensure they are snug.

Line Level: Verify that the line is evenly distributed across the spool. It should not be too loose or too tight. Make any necessary adjustments to ensure an even line lay.

Casting Test: Before heading out for your fishing trip, practice some casts to ensure the line is smooth and without tangles.

 If you encounter any issues, adjust the line tension and spooling further.


 The use of mono backing in combination with a braided fishing line can greatly enhance your angling experience and performance.

Mono backing for the braided fishing line is vital to your angling setup. It offers several advantages, including cost savings, security, and shock absorption.
