Wide Fit Shoes: Complete Width Guide (2E, 4E, 6E)

Width is a separate axis from length — going up a size to fit a wide foot just gives you a shoe that's too long. This guide tracks width grades from AAA to 6E, each about 4.8mm apart at the ball of the foot. Most brands sell D (standard) only; if you have wide feet, the brand matters more than the size. New Balance goes all the way to 6E.

Width-first finder

Enter your US size, ball width and target brand. The result keeps length and width separate, then tells you whether that brand stocks the width grade you likely need.

Width is its own axis: D, 2E, 4E and 6E are not extra length. New Balance size guide

The width grades, in millimetres

Each grade is one half-width step — about 4.8mm at the ball — measured from the standard width D (offset 0). Negative offsets are narrower than standard, positive are wider.

Width grades from narrow (AAA) to extra-wide (6E), with their approximate mm offset from standard D at the ball of the foot.
Grade Category Offset from D
AAA Narrow -19.2mm
AA Narrow -14.4mm
B Narrow -9.6mm
C Narrow -4.8mm
D Standard 0.0mm
2E Wide + 4.8mm
4E Extra wide + 9.6mm
6E Extra wide + 14.4mm

These are approximations — sources put the step anywhere from 1/8″ to 1/4″. We use ~3/16″ (4.8mm), the Brannock midpoint.

Which brands offer wide widths

For wide feet, the brand decides everything. New Balance is the clear leader (B through 6E); ASICS and Brooks carry wide and extra-wide running fits; Nike is essentially D-only outside of its FlyEase line.

If your brand does not stock your width

Do not automatically size up in length. One width step is about 4.8mm at the ball, while a half-size length change mainly adds front-to-back room. If a D-only brand squeezes the forefoot, the cleaner fix is a brand that actually stocks 2E, 4E or 6E.

  1. Keep the length that matches your measured foot.
  2. Move to the nearest stocked width in the table above.
  3. If the brand only offers D, compare New Balance, Brooks or ASICS before sizing up.

How to measure your foot width

Width is measured at the ball of the foot — the widest point, across the base of the toes. Do it late in the day when feet are largest, and measure both feet.

  1. Stand on a sheet of paper with your weight evenly on the foot, so it spreads to its true width.
  2. Mark the widest points on each side of the ball of the foot, then measure the straight-line distance between the marks in millimetres.
  3. Compare that width against the standard for your length on our scale above — a measurement well above standard means you want a 2E or wider, in a brand that actually stocks it.

Pair this with our foot length guide — you need both length and width to land the right fit.
