Old Navy is the budget-friendly arm of the GAP family, and it has a reputation that precedes it: sizes run generous. Vanity sizing is real here — garments frequently measure larger than the chart suggests, especially in women's tops, dresses, and jeans.
Below are Old Navy's published body measurements and the practical adjustments shoppers consistently recommend, so the bargain you ordered actually fits like you pictured it.
How does Old Navy fit?
The consensus is clear: Old Navy sizes generously, and finished garments often measure a size or more over the label — independent tests have found pants measuring inches larger than marked. Basics and tees stay closer to true to size, but anything fitted is usually safer one size down.
- For a fitted look, size down one — especially in tops, dresses, and jeans.
- Basics like plain tees and sweats are closer to true to size; keep your usual size there.
- Anything labeled loose, relaxed, or oversized runs very big — size down at least one.
- Stretch denim relaxes further with wear; when between sizes, take the smaller.

Old Navy sizing FAQs
Does Old Navy run big?
Yes — Old Navy is one of the most consistently generous-sizing mainstream brands. Garments often measure a size or more larger than the label, particularly women's tops, dresses, and jeans. For a fitted look, most shoppers size down one.
Should I size down in Old Navy jeans?
Usually, yes. Old Navy jeans tend to run big in the waist and hip, and most washes have enough stretch to relax further with wear. If you're between sizes or the denim is stretchy, take the smaller size.
Is Old Navy sizing the same as GAP?
The published charts are similar — they're sister brands — but the actual garments are not. Old Navy cuts noticeably roomier than GAP for the same label size. If you wear a medium at GAP, an Old Navy small will often fit the same way.
Do Old Navy basics run big too?
Less so. Plain tees, sweats, and activewear stay closer to true to size, while fashion pieces — fitted tops, dresses, denim — carry most of the generous sizing. Treat the two groups differently when you order.
