What Does D Mean in Shoe Size?
D = men's standard (medium) width. It is the middle of the US width range—not narrow, not wide. A tag like 10D means length 10 with D width. Women's D usually means wide (standard is B).
Men vs women: same letter, different meaning
- Men: D = standard · B = narrow · 2E = wide
- Women: B = standard · D = wide · 2E = extra wide
- Need wider than D (men)? See standard vs 2E.
What D means on the tag
D describes width, not length. US 10D means size 10 with D width. Unmarked men's shoes usually assume D.
The Brannock device prints D at the standard width mark for men. Narrower letters run B/C; wider run E, 2E, 4E.
If D feels wrong
- Pinch at sides → try E or 2E same length.
- Heel slip with plenty of toe room → length may be long, not width.
- Women feeling tight in B → try C or D (wide), not automatically a larger band size in bras—that is a different system.
