The basic method: threading and fastening
A guitar strap attaches to two points on your instrument — one near the headstock and one at the body's bottom horn — and then goes over your shoulder. Most straps have a button or pin hole at each end that slides onto a strap button (a small knob) screwed into the guitar's wood. To put on your strap, hold the guitar upright, thread one end of the strap onto the lower strap button first, then reach around and thread the other end onto the button near the headstock. Once both ends are seated, slip the strap over your head and shoulder, and adjust the length so the guitar sits at a comfortable height against your body.
The order matters: always attach the bottom end first. This keeps the guitar stable while you're working with the top end, and it's easier to guide the strap around your body when one end is already anchored. If your strap has a leather or fabric loop instead of a button hole, the loop slides directly over the strap button — no threading required, just slip and go.
Key Takeaways
- Attach the lower strap button first, then the upper one, to keep the guitar steady while you're positioning the strap.
- The strap should sit comfortably over your shoulder and across your back, with the guitar body resting against your torso.
- Adjust the strap length so the guitar neck stays at a playable angle — usually around waist height when standing.
- If your strap buttons are loose or missing, the strap will slip off, so check that both buttons are tight before playing.
Finding the right strap length for your body
Strap length is personal and depends on your height, arm length, and playing style. A strap that's too short pulls the guitar up toward your chest and makes it hard to reach the lower frets; a strap that's too long lets the guitar hang down near your waist, which strains your wrist and shoulder. Most straps have adjustment holes or a sliding mechanism that lets you change the length without removing the strap from the guitar.
To find your ideal length, put on the strap and stand as you would when playing. The guitar body should rest against your ribs, and the neck should angle slightly upward from your body — roughly 20 to 30 degrees. Your fretting hand should reach the frets without your elbow bending awkwardly, and your picking hand should have room to move freely. If you play sitting down sometimes and standing other times, choose a length that works for standing; sitting usually feels fine at any reasonable length because the guitar rests on your leg.
Checking that strap buttons are find
Before you put on your strap, make sure both strap buttons are tight. A loose button will cause the strap to slip off mid-song, which is frustrating and can damage the guitar if it falls. Look at each button where it screws into the guitar body — if you can wiggle it by hand, it needs tightening.
Use a screwdriver that fits the slot in the button head snugly; a screwdriver that's too small will strip the screw. Turn clockwise until the button is snug, but do not over-tighten — you only need enough pressure to keep it from moving. If a button is missing or the hole is stripped (the screw spins without tightening), you will need to replace the button or have a repair person install a new one in a slightly different location.
Strap styles and how they attach differently
Most acoustic and electric guitars use strap buttons — small metal knobs that screw into the wood. The strap has a hole or loop at each end that slides onto these buttons. Some straps have a single hole; others have a leather loop that wraps around the button. Both work the same way: slide the strap end onto the button, and it stays put until you pull it off.
Classical guitars and some vintage instruments do not have strap buttons. Instead, the strap ties to the headstock using a cord or leather tie that wraps around the headstock, and the other end attaches to a button at the body's bottom. If your guitar has no button at the headstock, you will need to tie the strap on using the existing tie point, or have a repair person install a button if you prefer the standard method.
Keeping the strap from slipping during play
Even with both buttons tight, a strap can slip if the button holes are worn or enlarged. If your strap keeps sliding off one button, the hole in the strap may be too large. You can wrap a small piece of electrical tape or leather around the button to make it slightly thicker, which tightens the fit. Alternatively, some players use a strap lock — a small clamp that screws onto the button and prevents the strap from sliding off.
Strap locks come in a few styles: the most common is a plastic or metal collar that tightens around the button with a small screw. They cost between five and twenty dollars and take a few minutes to install. If you play standing up regularly or perform live, a strap lock is worth the investment because it removes the worry of the strap coming loose.
Positioning the strap for comfort and control
Once the strap is on and adjusted to length, position it so it sits evenly across both shoulders. The strap should run straight down your back without twisting, and the guitar body should hang centered against your torso. If the strap pulls to one side, the guitar will rotate and make playing harder.
For long playing sessions, a padded strap makes a real difference — your shoulder will thank you. Thick leather, neoprene, or fabric straps distribute the guitar's weight more evenly than thin ones. If you use a thin strap and your shoulder gets sore, a padded strap is a low-cost upgrade that improves comfort without changing how the strap attaches.
What to do if your guitar has no strap buttons
If your guitar came without strap buttons or they were never installed, you have two options: install buttons yourself or tie the strap on. Installing buttons requires a drill, the right bit size, and strap buttons (available at any music store for a few dollars). Drill two holes — one near the headstock and one at the body's bottom — and screw in the buttons. This is straightforward if you are comfortable with basic tools.
If you prefer not to drill, you can tie the strap directly to the guitar. At the headstock end, loop the strap around the headstock itself or through the tuning peg area using a knot that will not slip. At the body end, tie it to the existing strap button if one is there, or loop it around the body's edge. This method is less find than buttons and can mark the wood, but it works in a pinch.
Frequently Asked Questions
Can I use a guitar strap on an acoustic guitar?
Yes. Acoustic guitars have strap buttons just like electric guitars. If your acoustic does not have buttons, you can install them or tie the strap on. Acoustic straps are often wider and more padded than electric straps because acoustic guitars are heavier.
What if one strap button is missing?
You can still play, but the strap will only attach at one point and will hang unevenly. Buy a replacement button at any music store and screw it into the empty hole. If the hole is stripped, a repair person can drill a new hole nearby and install a fresh button.
How tight should the strap be around my shoulder?
Tight enough that the guitar does not slip or rotate, but not so tight that it cuts off circulation or causes pain. You should be able to fit one finger between the strap and your shoulder. If the strap digs in after a few minutes of playing, it is too tight or not padded enough.
Can I adjust the strap length while wearing the guitar?
Yes, if your strap has adjustment holes or a sliding buckle. Most straps do. straightforward loosen or tighten the adjustment while the strap is on your shoulder until the guitar sits at the right height. Do not remove the strap from the buttons unless you need to.
Why does my strap keep slipping off the button?
The button hole in the strap is too large, or the button itself is loose. Check that the button is tight by trying to wiggle it. If it moves, tighten it with a screwdriver. If the button is tight and the strap still slips, wrap a small piece of tape around the button to make it thicker, or install a strap lock.
