Your Zwift avatar is a virtual representation of yourself, and some people take that very seriously. Think of everything that goes into your avatar’s “look”–your jersey and shorts, headwear, hairstyle and color, skin color, sock style and length, shoes, gloves, sunglasses, facial hair… it’s a lot!

Zwift has a challenging job here, making a system that creates avatars people can feel good about.

What about the avatar’s actual body? Sure, your avatar is “decorated” with all the clothing and accessories listed above, but have you ever wondered how Zwift sizes avatars?

We did a little research to figure it out.

3 For Men, 2 for Women

Zwift’s avatar sizing is actually quite simple. There are only three avatar body types for men, and two for women. Here’s what they look like:

What determines which avatar you see? It’s the rider’s weight and height. It appears body types change at a particular BMI.

Men’s Avatar Sizing:

  • Small: BMI <21
  • Medium: BMI 21-26
  • Large: BMI >26

Women’s Avatar Sizing

  • Small: BMI <22
  • Medium: BMI >22

That’s it. Your body parts don’t slowly grow larger or smaller as you change weight or height–you are given one of three (or two if you’re female) body types based on your BMI.

Example: men with a BMI of 26 or more will all have the same avatar body. Even if your BMI is 40 it will look the same as someone with a BMI of 26.

About Height

Your height setting affects your speed in Zwift and helps determine (along with weight) which avatar body type you get. But it does NOT change the visual height of your rider in game.

All avatars are the same height, regardless of your setting. This was probably done so kits and bike frames wouldn’t need to be scaled for each rider, but wouldn’t it be cool if you could see people’s actual size in game? It would add some nice variety to the visuals.
