What size bike for 6'0" (183 cm)?
Six feet tall puts you right on a boundary in several charts. Here's how to call it.
Short answer: at 6'0" you're usually a large, sometimes an XL: about a 56–60 cm road frame (by effective top tube) and a large mountain bike with a 19–20 in frame.[1 2 · Oct 29, 2026] Brands split this height differently, so check the exact model's chart and your inseam.

Large or XL?
- Long torso or arms for your height, or you like stability at speed: the longer reach of the bigger size may suit you.[5 · Oct 29, 2026]
- Short torso or arms, or you like a nimble, playful bike: the smaller size.[5 · Oct 29, 2026]
- Newer riders may find sizing up gives them more bike than they can comfortably control.[2 · Oct 29, 2026]
- Test ride both sizes if you can.[1 4 · Oct 29, 2026]
