Use Gap's current U.S. size charts as your starting point, then verify the item-level size guide before you order. Gap's official women's tops, outerwear, and dresses chart, women's jeans and inseam chart, men's tops chart, and men's bottoms chart are body-measurement guides, while Gap also notes that garment inseams live in product descriptions.

How Gap sizing works
The current guidance on Gap's size charts page is to measure yourself first and use the chart that matches the category you are buying. That matters because jeans, tops, and tall fits are not all labeled the same way, and the exact cut or fabric can still change how a piece feels on body.
Women's tops, outerwear, and dresses
Gap uses the same body-measurement scale across its current women's tops, outerwear, and dresses chart.
| Gap size | US size | Bust | Waist | Hip |
|---|---|---|---|---|
| XXS | 000-00 | 30.25-31.25 in | 24-24.75 in | 33.25-34.25 in |
| XS | 0-2 | 32.25-33.25 in | 25.5-26.5 in | 35.25-36.25 in |
| S | 4-6 | 34.25-35.25 in | 27.5-28.5 in | 37.25-38.25 in |
| M | 8-10 | 36.25-37.25 in | 29.5-30.5 in | 39.25-40.25 in |
| L | 12-14 | 38.75-40.25 in | 32-33.5 in | 41.75-43.25 in |
| XL | 16-18 | 42-43.75 in | 35.5-37.5 in | 45.25-47.25 in |
| XXL | 20-22 | 45.75-47.75 in | 39.5-41.5 in | 49.25-51.25 in |
Women's jeans and inseams
Gap separates women's bottoms by jean number and inseam. The current official chart also says to use product descriptions for garment inseams when you need item-specific detail.
| Gap size | Jean size | Waist | Hip |
|---|---|---|---|
| XXS | 23-24 | 23.5-24.5 in | 33.25-34.25 in |
| XS | 25-26 | 25.5-26.5 in | 35.25-36.25 in |
| S | 27-28 | 27.5-28.5 in | 37.25-38.25 in |
| M | 29-30 | 29.5-30.5 in | 39.25-40.25 in |
| L | 31-32 | 32-33.5 in | 41.75-43.25 in |
| XL | 33-34 | 35.5-37.5 in | 45.25-47.25 in |
| XXL | 35-36 | 39.5-41.5 in | 49.25-51.25 in |
| Length | Official inseam |
|---|---|
| Extra Short / Petite | 29 in |
| Short | 30 in |
| Regular | 31.5 in |
| Long | 33.5 in |
| Extra Long / Tall | 35.5 in |
Men's tops and outerwear
Gap's men's tops chart is driven by chest, neck, and sleeve measurements.
| Gap size | US size | Chest | Neck | Sleeve |
|---|---|---|---|---|
| XS | 36 | 35-36 in | 13.5-14 in | 31-32 in |
| S | 38 | 37-38 in | 14-14.5 in | 32-33 in |
| M | 40 | 39-41 in | 15-15.5 in | 33-34 in |
| L | 43 | 42-44 in | 16-16.5 in | 34-35 in |
| XL | 47 | 45-48 in | 17-17.5 in | 35-35.5 in |
| XXL | 51 | 49-52 in | 18-18.5 in | 35.5-36 in |
| XXXL | 55 | 55 in | 18.75 in | 36.5 in |
Men's bottoms
For men's pants and jeans, Gap mainly maps size to waist range.
| Gap size | US waist | EU size |
|---|---|---|
| XS | 28-29 in | 38-39 |
| S | 30-31 in | 40-41 |
| M | 32-34 in | 42-44 |
| L | 35-37 in | 45-47 |
| XL | 38-41 in | 48-51 |
| XXL | 42-45 in | 52-55 |
Petite, tall, short, and long
Gap's current women's jeans guide says petite is designed for 5'4 and under and tall for 5'9 and up. On the men's side, Gap's Tall Fit Guide says to order your regular Gap size when the chest and shoulders fit, but the regular shirt is too short in body or sleeves.
| Tall fit adjustment | Gap's current guide |
|---|---|
| Men's M-XL body length | 2 in longer |
| Men's XXL-XXXL body length | 1.5 in longer |
| Men's long-sleeve arm length | 1 in longer |
| Men's short-sleeve arm length | 0.5 in longer |
How to measure yourself the Gap way
- For bust or chest, measure around the fullest part.
- For waist, measure at the natural waist for women's bottoms or where your pants usually fall for men's bottoms.
- For hips, stand with heels together and measure the fullest part.
- For sleeves, bend the arm and measure from the back of the neck across the shoulder to the wrist.
- If you do not have a tape, Gap says a piece of string or ribbon and a ruler will work.
Practical fit checks before you order
- Use the category-specific chart, not a single size assumption across jeans, dresses, and shirts.
- If you are choosing denim, check both the waist or hip row and the inseam row.
- If length is usually your problem, compare regular versus petite, long, or tall before changing waist size.
- If you are between sizes, check the product page because fabric stretch and silhouette can change how close the chart feels in practice.
Bottom line
Gap's current U.S. charts are useful, but they are most reliable when you match the right chart to the right category and then confirm the individual product details. Start with your body measurements, use the official inseam or tall guidance, and treat the item page as the final fit check.
