Are guitar straps universal?
Guitar straps are close to universal for electrics, because almost every electric guitar and electric bass hangs from the same two fittings: a screw-in strap button at the tail and a second one at the neck end or on the upper horn. Any strap with a slotted hole at each end goes onto all of them. Most steel-string acoustics leave the factory with only the tail button, classical guitars have neither, and beyond that the variables are the length you need and the width your shoulder wants.
The button is the standard, and it is nearly always the same
There is no written standard that guitar makers sign up to, the way there is for a mains plug. What there is instead is a shape everyone copied: a small mushroom-headed screw, wider at the top than at its waist, so leather pushed over the head sits behind the flare and stays there. Head diameters across the common brands sit in a narrow band, about 12.5 mm across the head on the Gibson-style Gotoh button StewMac lists and about 14 mm on a Fender-style one, and a hole cut for one brand goes onto another without a fight. The Fender-style button is the larger of the two, which is why a stiff new strap can fight you on a Telecaster and go on a Les Paul more easily. Same hole, same strap. The leather has not given yet.
Strap locks rely on the same consistency. A Schaller or Dunlop set replaces the factory button with its own, and the pin that passes through the strap is sized for an ordinary strap hole. Most straps that fit normal buttons take a lock pin, though a thick leather end can need the hole worked open. The strap lock guide covers when that is worth the ten minutes.

Where universal stops: length, width and the back
Fitting and suiting you are two different questions. A strap can go onto your guitar and still be wrong for you in three ways.
- Length. Straps are sold as a range, and the ranges differ. Most adult players land somewhere between 45 and 55 inches button to button, but a strap that only reaches 48 inches at full stretch is no use to a bassist who wears the instrument at hip height. Measure yourself before you judge a strap. How to measure strap length.
- Width. Two inches is the common width, 2.5 and 3 inches are sold for heavier instruments, and pressure on your shoulder is weight divided by width. The button hole is the same whatever the shoulder width, so width is a comfort choice, not a compatibility one.
- The back. A smooth nylon or coated back slides on a cotton shirt. A suede or rough-out back grips. Nothing about the buttons tells you which you are getting, and on a guitar that tips headstock-down it matters more than either of the other two.
Classical guitars and some acoustics have nothing to attach to
Classical and flamenco guitars are normally built with no strap buttons at all, because they are meant to be played seated with a foot stool or a cushion support under the leg. Straps sold for classical guitars work around that. Some hook into the sound hole, some pass under the body and clip at the back, and some tie around the headstock behind the nut. None of them is a two-button strap, and adding buttons means drilling into the end block and the neck heel, which is a repairer's job on a classical guitar because the heel screws into end grain and a hole takes value off the instrument.
Steel-string acoustics are split. Many have one button at the tail, built into the endpin, and nothing at the neck. The usual fix is a leather lace that loops around the headstock behind the nut, and players have done it that way for decades. The other route is having a repairer fit a second button into the neck heel, which is a drill bit and a screw, but the heel is structural, so it is worth paying someone. We cover both in attaching a strap to an acoustic.
Ukulele, banjo and mandolin
These are the instruments where a guitar strap most often does not work, and it is worth knowing why before you order one as a gift.
| Instrument | What it usually has | What people use |
|---|---|---|
| Ukulele | Often no buttons, sometimes one at the tail | A sound hole hook, or a loop that goes behind the neck. A two-button strap works only if both buttons have been fitted |
| Banjo | No buttons on most. The rim carries metal hooks and brackets | A strap with leather cradles or metal clips that grab the brackets |
| Mandolin | An endpin at the tail, no neck button | One end on the endpin, the other tied at the headstock or the scroll |
A guitar strap is also simply too long and too wide for most ukuleles. Even fitted with two buttons, a soprano uke on a wide adult strap looks and hangs wrong.
Headless guitars take an ordinary strap
Headless guitars carry two normal buttons like anything else, so the hardware question does not arise. What changes is balance. With no headstock and no tuners hanging off the end of the neck, the weight sits in the body, so the neck-end button does not have to sit out near the 12th fret to keep the neck up. Strap length is still whatever height you play at.
Electric and bass: the same strap, worn lower
Bass straps and guitar straps are the same product. The buttons match, the holes match, and there is nothing in a strap sold as a bass strap that stops it fitting a Telecaster. Two things differ in practice. A four or five string bass often weighs 9 to 11 lb, against about 7 to 9 lb for a Stratocaster-style solid body and 9 to 10 lb for a Les Paul, so a wider strap earns its place. Bassists also tend to wear the instrument lower, which means more length. Buy for the heaviest instrument you own and the longest setting you need, and the same strap covers the rest of the rack.
Where our strap fits
The Soldier double-layer cowhide strap has solid leather ends with one button hole in each, which is the ordinary shape, so it goes onto any guitar or bass with two strap buttons. The length is set by a row of slots on the tail, the way a belt works, so one strap covers seated and standing play. It comes in black, dark brown, tan and white at £54.95, with free UK delivery and 30 days to send it back.
It is not the answer for a classical guitar with no buttons, or for an acoustic with only a tail button, because both ends of it need something to go over. We do not sell headstock ties, extenders, clip-ons or strap locks, so for those you want a music shop rather than us. We also cannot give you a width figure yet, because the maker has not confirmed one and we asked on 14 September 2026. If the fit turns out wrong, the return postage is on us. The strap page lists everything we do know about it.
Questions
Are guitar straps universal?
Mostly. Any strap with a hole at each end fits any electric guitar, bass or acoustic that has two strap buttons, and nearly every electric and bass does. The exceptions are instruments with no buttons, such as classical guitars and most ukuleles, and acoustics that only have a button at the tail.
Do bass and guitar straps fit the same buttons?
Yes. There is no separate bass fitting. Straps sold for bass are usually wider and longer because basses are heavier and worn lower, but the button holes are the same and either strap goes on either instrument.
Will a guitar strap fit a ukulele?
Only if the ukulele has had two strap buttons fitted, and even then a full-size guitar strap is usually too long and too wide for it. Ukulele players generally use a sound hole hook, a loop that sits behind the neck, or a single-point strap on a tail button instead.
Are strap buttons a standard size?
There is no formal standard, but the common brands have converged. Head diameters run about 12.5 to 14 mm on the buttons the parts suppliers sell, and a strap hole cut for one goes over another. A new stiff strap on the larger button just needs working on.
Do all guitar straps fit all guitars?
No. They fit all guitars with two strap buttons, which is most electrics and basses. Classical guitars have none, many steel-string acoustics have only a tail button and need a headstock tie for the other end.
