Old Navy Size Chart

Old Navy size guide at a glance#

Old Navy uses standard US sizing and tends to run a touch large, so if you are between sizes you can usually size down. Women’s runs XXS to 4X (numeric 0 to 30), men’s XS to XXXXL, and girls, boys and kids sizes 5 to 20 by height. A women’s M fits a 36½ in (93 cm) chest and 29 in (74 cm) waist; a men’s M fits a 40 to 42 in (102-107 cm) chest. Every chart below lists inches and centimeters, and most include UK and EU conversions.

• Women’s numeric sizes sit in the numeric column of the tops and bottoms charts: a size 4 lines up with XXS (a 31½ in / 80 cm chest, 24 in / 61 cm waist), a size 8 with S (34½ in / 88 cm chest, 27 in / 69 cm waist) and a size 10 with M (36½ in / 93 cm chest, 29 in / 74 cm waist).
• Jeans and pants go by waist. Women’s: 27 in (69 cm) = S, 29 in (74 cm) = M, 31½ in (80 cm) = L. Men’s: 32 to 34 in (82-87 cm) = M, 36 to 38 in (92-97 cm) = L.
• Girls and kids: kids sizes 5 to 20 go by height, and the girls and boys charts split above size 8. A girls’ size 8 fits a child 53 to 55 in (135-140 cm) tall; a boys’ size 8 fits 51 to 54 in (130-138 cm). Odd numbers like 5 and 7 are kids sizes.
• Plus sizes: women’s charts run to 4X, a 58¼ in (148 cm) chest.
• Shoes: a women’s US 8 fits a 9.8 in (25 cm) foot; a men’s US 8 fits 10 in (26 cm).

Old Navy’s letter sizing is consistent across most lines, so measure once and use the same size for tops, bottoms and underwear. Sizes run generous, so size down for a closer fit or stay with your measured size for a relaxed one.

Frequently asked questions#

Does Old Navy run big or small?#

Old Navy tends to run a touch large. The brand uses standard US sizing, but many shoppers find the fit generous, so if you are between sizes, sizing down often gives a better fit. Always check the chart for the item you’re buying, since tops (by chest), bottoms (by waist) and underwear use different measurements.

What size is an Old Navy M?#

A women’s M fits a 36½ in (93 cm) chest and 29 in (74 cm) waist, which lines up with a numeric size 10. A men’s M fits a 40 to 42 in (102-107 cm) chest, or a 32 to 34 in (82-87 cm) waist in bottoms. In kids’ clothing, M is a size 8.

How does the Old Navy girls’ size chart work?#

Girls’ sizes 5 to 20 go by height. A girls’ size 8 (M) fits a child 53 to 55 in (135-140 cm) tall, and a girls’ 10 to 12 (L) fits 55 to 60 in (140-153 cm). Boys’ sizes use the same numbers but split above size 8: a boys’ 10 to 12 (L) fits 54 to 60 in (138-153 cm). Pick the chart that matches the child.

How do I measure myself for Old Navy clothing?#

Use a soft measuring tape over fitted clothing. Measure your chest at the fullest point, waist at the natural waistline and hips at the widest point, then compare against the charts above.

What if I’m between sizes at Old Navy?#

Go by fit preference: choose the larger size for a relaxed feel or the smaller size for a closer fit.

Does Old Navy offer different lengths in pants?#

Yes. Many pants and jeans come in multiple inseam lengths, so you can match the length to your height as well as the waist.

Can I return or exchange if the size isn’t right?#

Old Navy accepts returns and exchanges on unworn, unwashed items within its return window. Check the current policy before you buy.

Sizing tips#

• Measure over fitted clothing. Bulky layers add an inch or more and push you into the wrong size.
• Match the chart to the garment. Tops use chest and neck, bottoms use waist and hip; the same letter is cut to different measurements in each.
• Old Navy is part of the Gap family. If you shop both, compare against our Gap size chart; the measurements behind each letter size differ between the brands.
