It is possible to come up with some rough guidelines based on height, but these are only an initial starting point for a proper fit consultation with your local dealer. Each person’s physical dimensions and attributes (i.e. arm length, torso length, femur length, flexibility, etc.) are slightly different and can lead to different frame size needs even for people of the same height. The chart below can be used to find a starting point for you.
If you are in between two sizes it is often best to go with the smaller size. It is easier to make a smaller frame fit a little larger then it is to attempt the reverse. Fitting is an important process which directly affects the ride quality and comfort of a bike. Trek dealers are skilled at sizing and can help find the appropriate bike and size to fit each individual’s needs.

如果您介于两个尺寸之间，我们建议您使用较小的车架。 小的车架可以进行一些调整使之能适合您骑行。 舒适度是影响骑行质量的重要因素。 崔克经销商对于车架的选择方面富于经验，他们能帮助您找到适合您需要的尺寸。 请见“寻找经销商”

The same is true with kids’ bike sizing. While height is a good starting point it is no substitute having your local dealer view your child on a bike to determine what is the appropriate fit. This is especially important as kids’ skill levels can vary greatly. A child who is very skilled at riding a bike may be comfortable on a larger bike then a child of the same height who has just learned to ride without training wheels. The chart below can be used as a good starting point.
