Don’t Fret About Frets: Guitar Fret Sizes, Materials, Wear & Repair

Quick Answer: What Matters Most?

• Fret height affects how easily the string can be bent, vibrated, and fretted without the fingertip dragging heavily on the fingerboard.
• Fret width affects feel, wear life, and how much crown material remains for future leveling and crowning.
• Fret material affects durability, polish feel, service difficulty, appearance, and sometimes perceived attack. It is not honest to promise that fret material alone will transform tone.
• Fret condition matters more than fret size. A worn or uneven premium fret can play worse than a modest fret that is level, crowned, polished, and properly set up.
• Setup matters with frets. Nut height, neck relief, action, intonation, radius, string gauge, and fretting pressure all affect how frets perform.

GLS Note: If a guitar buzzes, chokes on bends, feels rough, plays sharp in the first position, or has deep fret grooves, the issue may be fret condition, nut height, relief, action, or setup—not necessarily the player.

Fret Anatomy: What the Parts Actually Are

A guitar fret has a visible rounded top called the crown, a stem called the tang, and small barbs that help the fret stay seated in the fret slot. The string should contact the top center of the crown. If the crown becomes flat, worn, or poorly shaped, intonation and feel can suffer.

Fret Height vs. Fret Width

Fret Height

• Taller frets can make bends, vibrato, hammer-ons, pull-offs, and light-touch playing easier because the fingertip contacts less fingerboard wood.
• Lower frets can feel smoother for slides and chord movement, but once they wear too low, they can make clean fretting and bending harder.
• Too much pressure on tall frets can push notes sharp, especially for players with a heavy fretting hand.

Fret Width

• Wider frets often provide more material for future leveling and crowning, which can extend service life.
• Narrower frets can feel more precise and leave more visible fingerboard space, but they may wear through useful crown height faster depending on the player.
• Flat worn frets are a bigger intonation problem than wide frets by themselves. A properly crowned fret should have a clean string contact point.

Fret Size Comparison

Fret sizes vary by manufacturer and batch. Dunlop-style numbers such as 6230, 6105, 6150, 6100, and 6000 are useful references, but they should not be treated as universal across every supplier. Always verify actual crown width, crown height, tang width, and slot compatibility before refretting.

GLS Note: Fretwire numbers are reference families, not universal laws. Before a refret, the actual fretwire profile, tang width, slot width, fingerboard radius, and player preference must be confirmed.

Fret Materials: What Actually Changes

Fret material affects wear resistance, polish feel, workability, appearance, and sometimes perceived attack. The difference is usually more obvious under the fingers than through a mix, especially on electric guitars. Most modern refrets are done in nickel silver, stainless steel, or a gold-colored hardened copper alloy, but there are a few additional niche and historical materials worth knowing about.

GLS Recommendation: For most working players, the real choices are nickel silver, stainless steel, and a gold-colored hardened copper alloy. Brass, bronze, and historical iron/steel options are niche and should only be selected for a specific use case.

What About “Gold Frets”?

Gold-colored fretwire is not made of actual gold. It is usually a copper-based hardened alloy chosen for appearance, nickel sensitivity concerns, and durability between traditional nickel silver and stainless steel. Different brands market it differently, so always confirm the actual wire family, dimensions, and current availability before committing to a refret.

• Best reason to choose it: appearance, nickel sensitivity concerns, and a harder-than-nickel feel without going all the way to stainless steel.
• Best visual match: warm woods, gold hardware, certain acoustic guitars, boutique builds, and custom restorations.
• What not to assume: gold color does not mean actual gold, and it does not automatically make a guitar sound better.
• Availability warning: gold fretwire profiles and branding can change. Always verify current supplier availability before promising a specific wire type.

What About Pyramid or Triangular Frets?

Pyramid or triangular fret profiles are specialty designs with a narrow top contact point. They can offer a very defined feel and may appeal to certain custom or experimental builds, but they are not a standard solution for most players.

Claims that triangular frets make a guitar “perfectly in tune” should be treated carefully. A narrow contact point can help define where the string breaks over the fret, but intonation still depends on scale length, fret placement, setup, string condition, nut height, saddle position, string gauge, and the player’s fretting pressure.

GLS Recommendation: Most players are better served by a properly selected conventional fret size that is accurately installed, leveled, crowned, and polished.

Signs Your Frets Need Attention

• Deep grooves or dents under common chord positions.
• Flat fret tops where the original rounded crown has worn down.
• Buzzing in specific spots even after a reasonable setup.
• Notes choking out during bends, especially on the higher frets.
• Rough bends caused by dirty, oxidized, or poorly polished frets.
• Sharp fret ends from dry conditions or fingerboard shrinkage.
• Loose or lifting frets that move, click, or cause localized buzz.
• Poor intonation from worn crowns where the string no longer contacts a clean center point.

Fret Polish, Fret Level, Partial Refret, or Full Refret?

Important: A refret is not only “installing wire.” It can involve fret slot condition, fingerboard radius, binding, finish protection, nut adjustment, setup, and final fret leveling.

Choosing the Right Frets by Playing Style

• Beginner / general player: medium or medium-jumbo nickel silver is usually safe, familiar, and serviceable.
• Blues / rock lead player: medium jumbo, narrow tall, or jumbo frets can make bending and vibrato easier.
• Heavy-handed rhythm player: avoid extremely tall wire unless you can control fretting pressure; tall frets can pull notes sharp.
• Touring / high-hour player: stainless steel or harder gold/copper alloy wire may reduce long-term fret wear.
• Vintage restoration: choose wire that respects the instrument, the owner’s goals, and the existing fingerboard condition.
• Nickel-sensitive player: consider gold/copper alloy or other nickel-free options, depending on availability and fit.

The best fret is not the biggest or most expensive fret. The best fret is the size and material that support the player’s touch, tuning accuracy, maintenance expectations, and instrument value.

Used Guitar Buying Tip: Frets Can Change the Real Price

When buying a used guitar, fret wear matters. A guitar with deep grooves, uneven frets, or very low remaining fret height may still be worth buying, but the price should reflect the work needed.

A “good deal” can become expensive if it needs fret leveling, nut work, setup correction, electronics repair, or a refret immediately after purchase.

Common Fret Myths

• Myth: Bigger frets automatically give more tone. False. They can change feel and attack, but tone depends on the full instrument and rig.
• Myth: Stainless steel frets are always better. False. They last longer, but some players prefer the feel and serviceability of nickel silver or gold/copper alloy wire.
• Myth: Gold frets are actual gold. False. They are gold-colored alloys, usually copper-based.
• Myth: Pyramid frets make a guitar perfectly in tune. False. They may define a narrower contact point, but tuning still depends on the full setup and player pressure.
• Myth: Fret buzz always means low action. False. It can also come from uneven frets, loose frets, backbow, hardware vibration, or aggressive attack.
• Myth: A refret always hurts value. Not always. Poor work can hurt value; necessary, high-quality fretwork can improve playability. Vintage/collectible instruments should be evaluated carefully.

GLS Final Take

Frets affect feel first, playability second, and tone more subtly than many marketing claims suggest. The biggest real-world difference is not “which fret is coolest.” It is whether the frets are level, properly crowned, polished, seated correctly, and matched to the player.

If your guitar feels harder to play than it should, buzzes in certain areas, chokes on bends, has sharp fret ends, or has visible grooves in the frets, it is worth having the instrument inspected before assuming the guitar itself is bad.

Gannon Luthier Services can inspect fret condition, evaluate fret wear, perform setup work, polish frets, diagnose buzzing, and help determine whether a guitar needs fretwork or a full refret.

Frequently Asked Questions

Do bigger frets give more sustain?

Bigger frets can feel more responsive because the string contacts less fingerboard wood and bends more easily. However, sustain depends on many factors, including setup, string condition, pickups, bridge, nut, neck joint, and technique. Do not choose fret size based only on a sustain claim.

Are stainless steel frets always better?

No. Stainless steel frets last longer and feel very smooth, but some players prefer the feel of nickel silver or gold/copper alloy wire. Stainless is also harder to service and may increase refret cost.

Do worn frets cause tuning problems?

They can. Deep grooves, flat crowns, and uneven fret heights can affect intonation, buzzing, and note clarity. Nut height and saddle intonation also matter.

Can sharp fret ends be fixed?

Yes, sharp fret ends can often be dressed and smoothed. If the problem is caused by dryness and fingerboard shrinkage, humidity control should also be addressed.

Should I refret a valuable vintage guitar?

It depends on the instrument, originality, value, playability, and owner goals. A refret can improve playability but may affect collector value if done poorly or unnecessarily. Valuable vintage instruments should be evaluated carefully before any invasive work.
