Size finder

Find your Forever 21 size

Your measurements

Measure your body (not a garment) with a soft tape, snug but not tight.

Enter your measurements to see your Forever 21 size.

Fit tip: Forever 21 uses junior sizing that runs small and inconsistent, especially tops and jeans, so size up if between sizes.

How to measure
  • Chest / bust: around the fullest part, keeping the tape level.
  • Waist: around the narrowest part, usually at the belly button.
  • Hips: around the widest part of your seat.
  • Foot length: stand on paper, mark from heel to longest toe, then measure the line.

Use a soft tape over light clothing, snug but not tight. No tape measure? Scan yourself with the Size AI app.

Forever 21 size guide at a glance#

Forever 21 women’s sizes run XXS (0) to XXL (15): a M (7-9) fits a 35 to 36 in (89 to 91 cm) bust and a 27 to 28 in (69 to 71 cm) waist. Men’s sizes run XS to XXXL, kids’ 5/6 to 13/14. Jeans are sized by waist in inches.

What do Forever 21 jeans sizes convert to? The number is your waist in inches: a 28 is a 28 in (71 cm) waist. On the bottoms chart that puts a 26 in S (3-5), a 27 or 28 in M (7-9), a 29 in L (11) and a 30 or 31 in XL (13).

Does Forever 21 run true to size? Generally yes, though fit varies by style and fabric. Check the measurements on each chart against your own, and size up in non-stretch fabrics if you’re between sizes.

Frequently asked questions#

Are Forever 21 sizes true to size?#

They generally run true to size, but individual items and styles can vary. Always refer to the size charts and consider fabric stretch.
