How to choose a guitar strap
A good guitar strap carries the weight of the guitar without digging into your shoulder, and it stays where you set it instead of creeping toward your neck. Four things decide whether a strap does that: the material, the width, the length range it covers, and the finish on the back. Tooling patterns and brand names change how a strap looks, not how it wears, and most of the money above the cheap end of the market buys leather and stitching rather than comfort.
Material first, because it sets everything else
Almost every strap on sale is one of four things. Woven nylon or polypropylene webbing, the kind that comes in the case with a starter guitar, usually two inches wide with a plastic slider for length. Cotton or hemp webbing, softer on the face, otherwise the same idea. Leather, which is heavier and keeps its shape, and which takes the curve of your shoulder after a few weeks of use. And synthetic leather, which looks like leather on day one and tends to crack along the fold where it crosses the shoulder.
Material also decides how the strap adjusts, because webbing runs through a slider and leather runs through a row of slots cut in the tail. The leather versus nylon comparison goes through that trade properly.
What we sell: one strap, the Soldier double-layer cowhide strap, in black, dark brown, tan or white. Suede-finish back, length set through a row of slots on the tail. £54.95 with free UK delivery.
Width is about pressure, not strength
Strength is not the question. Webbing and leather both hold many times what a guitar weighs. When a strap does give way it is normally at the button hole, where the load bears on a small area of material, rather than across the middle. Width matters because pressure is weight divided by the area carrying it. Move the same guitar from a two inch strap to a three inch strap and the load on each inch of your shoulder drops by a third.
Most solid-body electric guitars weigh between about 7 and 9 lb, which is roughly 3.2 to 4.1 kg. Les Pauls often run 9 to 11 lb, which is about 4.1 to 5.0 kg, and a four-string Fender-style bass is usually 8.5 to 9.5 lb, or about 3.9 to 4.3 kg. At the light end of those weights a two inch strap is fine for an hour. At the heavy end, or across a three hour function gig, the wider strap is the difference between watching the clock and forgetting your shoulder is there. The 2 inch versus 3 inch guide has the arithmetic.
Length range matters more than any single number
Measure from the tail strap button, up over your shoulder, down to the neck button, with the guitar sitting where you actually play it. Most players land somewhere between 45 and 55 inches, and bassists tend to sit at the long end of that. That measurement is the one number worth taking before you buy anything.
The range is where straps go wrong. A webbing strap set near its longest is the one that slips, because only a short tail is left threaded through the slider. A padded strap has the pad fixed in one place, and most of them adjust at the tail only, so shortening one drags the pad off the top of your shoulder instead of leaving it where the weight is. A slot-adjusted strap is the same shape at every setting. Check the published minimum as well as the maximum, because a shorter player on a long-only strap has no way out of it. The length guide covers the measuring.
The back of the strap is the part nobody looks at
Product photos show the face of the strap. The back is what touches your shirt, and it decides whether the guitar stays at the angle you set. Suede and rough-out leather grip cotton. Smooth nylon slides on it, and so does glossy finished leather and most synthetic pad lining. If the strap walks toward your neck over a set, the back of the strap is usually why. Neck dive is a separate problem that comes from where the guitar's balance point sits relative to the front strap button, and a grippy back holds a neck-heavy guitar where you put it rather than curing the balance. The neck dive fix deals with the balance side of it, and the back is still the variable buyers think about last.
What each price band buys in the UK
At the bottom of the market you get plain woven nylon with a plastic slider, stocked by most UK music shops and included in most beginner guitar packs, though a guitar bought on its own rarely comes with one. It is light and it washes, and it takes years of ordinary use before the webbing or the slider shows wear. For a lot of players that is the right answer. A cheap nylon strap on a light guitar played sitting down at home is not a problem worth spending money to fix.
The middle band buys thicker webbing, printed designs, a name you recognize and usually some padding. The comfort gain over plain nylon is real on a heavy guitar and slight on a light one. The top band is leather, single layer or double layer, with stitched edges and slot adjustment. That is the band ours sits in, at £54.95. What the extra money buys is a strap that keeps its shape, and a back that grips your shirt when it is finished as suede.
The features that sound good and change nothing
Strap locks are mostly a guitar part, not a strap part. A set is two pieces: a button that replaces the one on the guitar, and a retainer that bolts through the hole in the end of an ordinary strap, so it is a decision you can make later or never. On thick leather, check that the set you buy is rated for the thickness. We do not sell them, and most music shops do. The strap lock guide says when they earn their place.
Padding on a strap with a slippery synthetic back trades one problem for another. Genuine leather on a label is not a quality grade. The US FTC Leather Guides at 16 CFR Part 24 only govern when a product may be called leather at all, split hide included, and no UK rule grades it, so the phrase is used on coated split hide as readily as on anything better and tells you very little about how a strap will wear. Tooling and embossing are decoration, and so is contrast stitching. None of that is a reason to avoid a strap, it is just not a reason to pay more for one.
Where our strap fits, and who should not buy it
The Soldier double-layer cowhide strap is our answer in the leather band: two layers of cowhide stitched down both edges, a back finished as suede, no padding, and the length set through a row of slots on the tail. Soldier makes it and Setlist Straps is the UK retailer, which we print on the page rather than leave for you to work out. We do not publish its width or its adjustment range, because the maker has not confirmed either figure and we asked on 14 September 2026.
Do not buy it if your acoustic has only a tail button, because both ends are button holes and you would also need a headstock tie, which we do not sell. Do not buy it if you want padding, because there is none in it. And if the nylon strap already on your guitar is not bothering you, the honest advice is to keep it and spend the money on strings. If the leather is what you are after, the strap page lists the colors and what the price covers.
Questions
What is a good guitar strap?
One that spreads the weight of the guitar over enough width that you stop noticing it, and whose back grips your shirt so the guitar stays at the angle you set. Material, width, length range and the back decide that. Price tracks those four only loosely.
Are guitar straps universal?
Nearly. Almost every electric guitar and bass uses the same size strap button at both ends, so most straps physically fit. Length and width are where straps differ, and an acoustic with only a tail button needs a headstock tie as well as a strap.
How wide should a guitar strap be?
Two inches suits most electric guitars under about 8 lb, which is roughly 3.6 kg. Two and a half to three inches earns its place on a Les Paul, a bass, or any gig past an hour. Bass players often go wider again.
How much should I spend on a guitar strap?
Enough to get a back that grips and a width that suits the guitar you own. The cheapest woven nylon straps do not always give you either. A leather strap with slot adjustment costs more and has fewer parts in it that wear out. Plenty of people are well served by the cheap one.
