Guitar Strap Keeps Falling Off? 4 Causes and the Fix for Each
A strap that pops off is a dropped guitar waiting to happen, and a fall onto the headstock can crack the neck. Find which of four causes you have - most are free or cheap to fix.

Quick answer
1) Strap hole stretched: rubber strap washers, or a new strap. 2) Button too small or shallow for a thick strap: washers now, strap locks for good. 3) Button screw loose: snug it up; if it spins in a stripped hole, get the hole repaired before you play standing. 4) Strap slides off your shoulder: a wider or grippier strap. For gigging or heavy guitars, strap locks are the permanent fix.

Cause 1: the strap hole has stretched
First, which is falling: the strap off the button, or the strap off your shoulder? The first is causes 1-3; the second is cause 4.
Leather and suede strap holes stretch with use until they slide over the button head. Test: push the strap onto the button and pull it straight off without twisting - if it comes off easily, the hole is the problem. Cheap fix: rubber strap washers pressed over the strap onto the button (some players use the rubber seal from a flip-top bottle the same way). Permanent fix: a new strap with snug holes, or strap locks.
Cause 2: button and strap do not match
Some guitars ship with small or shallow buttons, while thick leather straps need more room under the button head. Many acoustics have only one button at the tail; tying the other end behind the nut is traditional but slips more. Adding a neck-heel button means drilling into the heel - location matters on an acoustic, so ask a tech.
Cause 3: the button itself is loose
If the button wobbles, tighten the screw gently with a screwdriver that fits the head exactly - snug, not cranked (over-tightening strips the wood). If it keeps turning without tightening, the hole is stripped. The common quick fix (shown by StewMac) is to glue hardwood toothpicks into the hole, snap them flush, let the glue dry, then re-drive the screw snugly; the more permanent repair is drilling out the hole, gluing in a hardwood dowel and drilling a fresh pilot hole. Some techs use a drop of thin CA glue instead of wood glue. It is simple woodwork, but it is woodwork on your guitar - for anything valuable, vintage or with a delicate finish, have a tech do it. Do not keep playing standing with a button that spins.
Cause 4: the strap slides off your shoulder
Slick nylon or polypropylene webbing can slide off the shoulder rather than the button, especially with a neck-heavy guitar. A wider strap, a grippier material (cotton, suede, leather) or a non-slip shoulder pad fixes that. Our straps guide compares materials and widths.
The permanent fix: strap locks
Strap locks replace your strap buttons with locking buttons and fit a matching clip to each strap end, so the strap physically cannot slide off. They are the most direct product answer to this exact problem. Two established systems: Schaller S-Locks (pull-pin release; Schaller lists them for straps up to 6mm thick) and Dunlop Straplok (button release). Installing usually means swapping the existing buttons; if the new screws do not suit the old holes, a tech is safer than forcing them. Gibson's how-to for installing strap locks covers the steps: remove the old button, check the screw size and pilot hole, fit the new button snugly, and attach the strap-side clips. Locks solve causes 1 and 2 - a stripped screw hole still needs repairing first.

If the strap itself is the problem
Two inexpensive catalog straps that replace a stretched or slippery one - a 2in polypropylene Levy's and Ernie Ball's polypro strap. If shoulder slip is your issue, compare grippier materials in the straps guide before buying.

FAQ
Why does my guitar strap keep falling off?
Usually a stretched strap hole, a button too small for a thick strap, a loose button screw, or a slippery strap sliding off your shoulder. Each has a different fix.
How do I stop my guitar strap from falling off for free?
Rubber strap washers pressed over the strap on the button are the cheapest fix. Check and gently tighten the button screws too.
Are strap locks worth it?
If you play standing, gig, or have a heavy guitar, yes - they stop the strap sliding off. They do not fix a stripped screw hole.
My strap button screw keeps coming out. What do I do?
If the hole is stripped, it needs filling with wood and glue and the screw re-driven. On a valuable guitar, have a tech do it.
Can I add a strap button to my acoustic?
Yes, but it involves drilling and the location matters, so a tech is the safest route.
