All About Frets Part 3: What Size Fret Should I Choose?

We handle a lot of refrets at the shop these days so we have gotten well-versed in helping people find the right fret for them. If you are researching what frets are right for you guitar, then you have come to the right place! 

Fact: Size Matters! However, when it comes to frets, only two dimensions matter to the Player and they are height and width.

The 2 dimensions that matter most: Height and Width

The Length of a fret is determined by it’s position on the fretboard. Since most/all necks get wider as you work your way up the frets, the 1st fret is considerably shorter than the 20th fret. For example a typical Tele will have 1.650" nut width while the Butt Width (the width of the neck after the last fret) is 2.2". Each fret has to get a little longer to keep up with the widening of the fingerboard.

So, Height and Width are the two determining factors that shape how a fretboard feels/plays. Depending on how you play, and your expectations or the intended use of a specific guitar, we would cater our recommendation of fret size.

Before we get any further, let’s get on the same page about 2 very important things to make this conversation easier since frets and action are tied together in most conversations from our experience.

1. Action is the distance between the crown (tippy top) of the fret and the bottom of the string, NOT FROM THE FINGERBOARD TO THE BOTTOM OF THE STRING. Read that again, digest it, accept it, and move on. If you want the tallest fret you can find, then your action will only appear higher than if you picked something shorter because of its greater distance off the fingerboard. However, with a properly set-up guitar and a properly slotted nut, the height off the fret should be the same regardless of fret size as long as the tech is competent. Again, just to reiterate, action is the distance between the bottom of the string and the tippy top of the fret.

2. If your fingerboard is finished (like a maple Fender or rosewood Rickenbacker), then a considerable amount of fret height will be lost due to the finish. That accounts for why the same fret size feels shorter on an unfinished fingerboard than on a finished one (think Rosewood vs. Maple). In other words, what you like on a finished fingerboard feels shorter than that same fret will feel on an unfinished fingerboard.

Now let’s get into which size fret you should choose?

A Short and Thin fret will appeal to both Vintage Fender and 1950s Gibson Enthusiast’s since those frets were most common on early electric guitar examples. While these frets tend to make Modern Player’s cringe, I’ll admit I have had my bias against them in previous years, I have grown to appreciate their place in the mix. These frets allow for seriously low action and are a bar-chorders best friend. They don’t allow for getting under the string very easily so many people find bending or vibrato on these frets to be more difficult than a Wider fret.

Short and Thin Fret Examples: Dunlop 6330-6320-6310, Jescar 37053, Jescar 39040, Sanko SBU-23, also called Vintage Fret Wire.

Guitars that have them: Vintage Fender’s prior to the 1980s, 1950s Gibson Electric guitars, the Fender Eric Clapton Stratocaster features these frets as well.

A Short and Wide fret will provide the player with more surface area of the fret making contact with the string. This fret will allow for easier bending and vibrato than the Short and Thin fret but still not as good as a Tall fret that buys you a little Real Estate between the fingerboard and string. An extreme example, the Gibson Fretless Wonder. They had extremely low frets that have been flattened out on top and they require very little pressure to get a note to sound. Leads are fast on these guitars but you are always dragging on the fingerboard a bit. Bending is tough, as is vibrato but if bending ain’t your thing, these frets will certainly not slow you down.

Short and Wide Fret Examples: Dunlop 6230 or 6290, but they still need to be 'crowned down' to achieve true Fretless Wonder height. Jescar 39106, 45100, 47104 and Sanko SBB213 (thanks, Joe Martin!).

Guitars that have them: 70s era Gibson Fretless Wonder LP Customs, other Gibson’s of the 70s and 80s saw considerable reduction in fret height but not to fretless wonder levels, some Mosrite Guitars, other assorted odd birds from the 70s. This style is not in fashion at the moment so no manufacturers that we deal with are using them.

A Medium Height and Medium Width provide great playability potential, which makes bends and vibrato easier by allowing you to get ‘under’ the string easier. This sized fret, often called Medium-Jumbo, provide enough width  and height that bending and vibrato don’t suffer. This is the size fret I chose for my own builds as I find they have the perfect blend of dimensions for my slightly heavy left hand.

Medium Height and Medium Width frets: Jescar 47095, 47090, and 45080 are all great options. As are the Sanko SBB-217 or SBB-23. The Jim Dunlop 6150 is quickly becoming a shop favorite.

Guitars that have them: Lots of Fender Custom Shop guitars, many American Made Fenders utilizing Narrow-Tall frets. Many acoustics go for frets in this size range as well. Most Martin and Taylor guitars are outfitted with the smaller frets in this size range.

A fret with Tall Height and Medium Width can be tricky for some as it makes playing sharp fairly easy due to their height. Fretting too hard will result in your guitar sounding out of tune. However, for those that can handle them, it's a great feeling fret that allows for fast play, easy bends, and helps keeps your fingers off the fingerboard, reducing the potential for needless drag. Some consider these frets Narrow or Thin however since they come in at .090 wide and there are thinner choices out there (as thin as .053), so I'm comparitively classifying them as Medium-Width.

Frets with Tall Height and Medium Width: The most popular choice is Dunlop's 6105 and the Jescar equivalent would be the 55090. 

Guitars that have them: This is easily one of the most popular choices for Fender Custom Shop guitars and by those getting their guitar refretted.

Medium Height and Wide Width frets start getting into the bigger frets. Frets this large also carry the term Medium Jumbo. Frets this big will require what appears to be slightly higher action in order to compensate for the extra fret height. However, remember that action is measured from the top of the fret to the string so that “extra” action is just a matter of incorrectly calculating the distance.

Medium Height and Wide Width Examples: Dunlop 6155, 6110,  Jescar 51100, 51108, Sanko SBB-221 or SBB-214.

Guitars that have them: PRS Guitars have been using them all along, Jackson, Charvel, Ibanez, and many other Shredder type guitars have these frets as well.

Tall Height and Wide Width frets tend to be called Jumbo Frets. These frets get called everything from bass frets to railroad ties and they certainly provide any guitar with enough height to execute a couple level and crowns before you run out of material. While these frets will buy you time in-between refrets they start out pretty darn high, which as we have learned, means your action will also be high.

Tall and Wide Fret examples: Dunlop 6000-6100, Sanko SBB-215, SBB-221, and SBB-213. Jescar’s 57110 and 58118.

Guitars that have these frets: Basses, again, Jackson, Charvel, Ibanez, many shred-friendly guitars.

Obviously there are enough options to make selecting a fret confusing and difficult. Paralysis by analysis is an all to common result for the average player once they delve into this surprisingly deep topic. What frets will allow you to play your best? Well, that’s a question only you can answer. The best way to answer that question is by playing a handful of guitars with the intent of focusing on how the frets affect playability. However, some pre-emptive introspective thought can go a long way and if you find that you are a rhythm player that sticks to chords, maybe those medium-jumbo’s have been working against you? 

So, after all this, hopefully you have a better understanding of frets, how they impact playability, and a little more direction about what will and won’t work for you. And if not, worry not! We can measure the existing frets on your guitar and find a suitable replacement. 

A couple of parting ideas and things to remember…

  • Get a new nut when you refret a guitar for best possible set-up. After a level and crown, a good tech will lower your nut slot height to match the new height of your frets. These lowered nut slots probably won't allow your strings to clear the 1st Brand New Fret. So, nut up!
  • REMEMBER! Action height is measured from the top of a fret, NOT the fingerboard! So the perception is that on shorter frets, the action is lower but barring proper set-up this is a fallacy!
  • Pick your material wisely. Stainless may last forever but it may ruin your tone! Also, many luthiers won’t work on stainless since it is rough on tools.

  • Hi Mathew.
    My 2015 Gibson True Historic Goldtop has narrow tall frets.
    I’m thinking about replace them with Jescar 47104.
    The reason is to make bends easier and prevent my fingers from rubbing on the fingerboard.
    Will I feel a big difference with the change?
    Do you have any recommendations?
    Thank you so much.

  • Hi,
    Thanks for the article – just not sure where the narrow-tall fret fits in?
    Cheers

  • Hi Matt, thank you for this very informative blog post. Just wanted to clarify something, as I was looking at putting Sanko’s SBB-213 fret wire on my guitar…

    You have SBB-213 in the “short and wide” category, but according to Sanko’s website, it has a height of 0.039”. In fact, it appears that SBB-213 has the same height and width dimensions (0.039” and 0.106”, respectively) as Jescar’s 39106 which you provide as a “short and wide” example.

    I suppose this is all a moot point since your blog post helped me discover that Jescar’s 39106 will also work for me and is far more readily available from what I can tell. But just for the sake of accuracy I thought you might want to consider putting SBB-213 in the “short and wide” category?

    Thanks again for compiling all of this helpful info.
