GAP vs Levi's Sizing: Measurement-Based Comparison

GAP and Levi's don’t always use equivalent size labels or measurements. This comparison uses available brand measurement data to identify where one brand appears roomier than the other. Results are shown separately by gender and category, since the relationship between the two brands can differ between tops and bottoms.

Quick summary

GAP vs Levi's sizing varies by category.

Men: Levi's appears roomier for tops, with moderate evidence, while bottoms and footwear line up closely. Footwear has the strongest evidence.

These results apply to the categories shown here, not necessarily to other clothing types.

“Evidence” here means how many sizes were compared and how consistently they agreed, not a guess. See the category breakdown below for the specific findings.

How this comparison works

We compare the brands’ published size-chart measurements within the same clothing category. Small differences within a normal measurement tolerance are treated as effectively equal. Evidence strength depends on how many comparable sizes are available and how consistently the results point in the same direction. Closest measurement matches show the nearest chart values, not a guaranteed fit.

Bottom line

Women: Tops and footwear line up closely.

Men: Levi's appears roomier for tops, while bottoms and footwear line up closely.
