Estimates, not guarantees

Every calculator on 7TShirts — t-shirt, bra, shoe, pants, kids, ring, and hat sizing — produces an approximate recommendation based on standard, publicly available measurement charts. These charts represent industry averages, not any single brand's exact specification.

Brands vary

Two garments labeled the same size from two different brands can fit noticeably differently, because each brand uses its own block pattern, fabric, and fit philosophy. Whenever possible, cross-check our result against the specific brand's own size chart before purchasing.

Not medical advice

The bra size calculator and any body-measurement tools on this site are provided for clothing-fit purposes only. They are not medical advice and should not be used to diagnose, monitor, or treat any health condition.

Use your judgment

If a result feels off compared to your own experience with a brand, trust your experience — and let us know via our Contact page so we can look into it.
