How Long Should a Replacement Bag Strap Be?

Typical situation

You are replacing a broken shoulder strap and you want to carry the bag crossbody, but you do not know how long to cut the new strap.

Main answer · berabags Editorial Team · Repair view

Decide how you will carry the bag, measure the length on your body, and add the folds at each end. The iFixit purse strap guide tells you to make sure the strap is the right length for your carrying preference, such as crossbody, one-shoulder or crook of the elbow.

What the guide says

Measurements will vary depending on preference.
The guide’s example is a one-shoulder strap.
The end of the strap is folded over, and there should be about half an inch to an inch of room for sewing.
Make sure there is enough strap between the attachments for you to carry the bag.

How to measure

Hold the bag where you want it to hang.
Run a tape measure from one attachment, over your shoulder, to the other.
Add the fold allowance at both ends, about one to two inches in total.
Add a little extra if you wear thick coats.
Cut the strap, then test the length before the final stitching.

Types of carry

Hand or elbow: a short strap, which lets the bag sit near your hip.
One shoulder: a medium strap.
Crossbody: a longer strap, going over the head.
Adjustable straps: the buckle or slider adds a small amount of length to allow for.

If you are unsure, borrow a strap or a length of ribbon and try the bag at several lengths in front of a mirror. Mark the length that sits where you want it, then use that mark to cut the new strap, so you do not rely on guesswork.

Where this answer stops

The guide gives the principle but no standard measurements, since these depend on your height and preference. Try the length with the bag loaded.

Measure with the bag in place, over the clothes you usually wear. A strap that fits over a thin shirt may be too short over a winter coat, so test over the thickest layer.

Cut the strap longer than you need and trim it later. A strap that is too long can be shortened, but one that is too short has to be replaced.

Allow for the folded ends. The iFixit guide leaves a half inch to an inch to fold over and sew at each attachment, and that has to be added to the length you want.
