Jordan Shoe Sizing Guide: Do They Run Small?
Jordan Brand shoes run about half a size small and narrow — the same recommendation as most Nike lasts, since Jordan shares Nike's performance-oriented engineering. Size up half a size from your usual US size, and budget for width: the D-width-only range is unforgiving for wide feet.
Across our data Jordan runs small: 50% of wearers report it runs small, 42% true to size and 8% large.
Jordan sizing philosophy
Jordan Brand is a subsidiary of Nike and inherits Nike's lasts and grading conventions, so the sizing logic is similar: a relatively narrow, low-volume profile designed to lock the foot in place for explosive movement. The Air Jordan 1, now a lifestyle icon, was originally a basketball shoe tuned to Barleycorn sizing — slightly tighter than a dress shoe, slightly roomier than a running flat — and that calibration persists across the retro range.
The model range spans basketball-heritage silhouettes (AJ1 through AJ36) and lightweight performance shoes (Jordan Why Not, Luka). Within that range, the vintage and retro silhouettes tend to fit narrower and smaller than the modern performance runners, because retro tooling is preserved intact rather than updated to modern standards. Knowing which era a Jordan belongs to matters more than knowing the brand.
How Jordan models differ
There is no single "Jordan size" — different lines are graded on different lasts. Here is how the key models compare:
- Air Jordan 1 (Low & Mid)
- The volume reference: narrow through the midfoot, slightly small. Half a size up is the standard move, or true to size if you like a snug feel.
- Air Jordan 4 / 11
- Slightly roomier than the AJ1 due to a different tooling design; many buyers go true to size, though the narrow D width is still a factor for wide feet.
- Jordan Why Not / Luka (performance)
- Modern performance lasts that fit true to size and are more accommodating of different foot shapes than the retro silhouettes.
Practical sizing advice
If you normally wear US 9, start by checking Jordan in US 9.5 — especially for retro silhouettes like the AJ1 where the narrow last amplifies the small fit.
If your feet are wide
Jordan Brand is exclusively standard (D) width, with no wide-grade option across any silhouette. Wide-footed buyers will feel the narrow toe box quickly, particularly in the low-volume retro silhouettes — sizing up half a size helps with length but does not solve the width problem.

This table starts from the US size you wear in a true-to-size brand, converts it to a foot length, and applies Jordan's measured fit so you can see the first size to check — plus the UK, EU and CM equivalents.
| You normally wear (US) | Foot length | Check Jordan (US) | UK | EU | CM |
|---|---|---|---|---|---|
| US 7 | 246mm | US 7.5 | 6 | 37 | 24.5 |
| US 8 | 254mm | US 8.5 | 7 | 38 | 25.5 |
| US 9 | 262mm | US 9.5 | 8 | 39 | 26 |
| US 10 | 271mm | US 10.5 | 9 | 41 | 27 |
| US 11 | 279mm | US 11.5 | 10 | 42 | 28 |
| US 12 | 288mm | US 12.5 | 11 | 43 | 29 |
EU sizes are always rounded to a whole size — there is no exact half-size equivalent. The recommended Jordan size applies this brand's average fit; individual models still vary, so check the model notes above.
