Finding the Right Bike Frame:

Finding the right bike frame is key to enjoying the ride ahead. A bike that's too large or small for your body leads to discomfort and a difficult ride.

Bike sizes are determined by a person's body dimensions. Cyclists should know their inseam length and exact height before purchasing a new frame. Weight is not a determining factor in your bike frame size.

Height: Measure yourself against a wall while standing on a flat surface.

Inseam: Follow these steps to determine the inside length of your leg, or inseam.

  1. Stand with your back against a wall and your feet spread 6 to 8 inches apart on a flat surface.
  2. Place a book between your legs to mimic a bike seat, with its spine facing upward. Raise the book upward until it is snug against your body.
  3. Have someone measure from the top of the book's spine down to the floor. This measurement is your inseam.

Next, consult the DICK'S Sporting Goods bike frame charts below. Use your height and inseam ranges to pinpoint your ideal bike frame size.

How to Size Your BMX Bike:

From motocross to stunts at the park, a BMX bike is built for action.

BMX bikes are lightweight yet sturdy, with compact wheels to handle maneuvers and tricks. While road and mountain bikes are sized by frame, your BMX bike is sized by the wheel.

At DICK'S Sporting Goods, BMX wheel sizes range from 16 to 20 inches. View the chart below, and use your height as a guideline to determine your wheel size:

Finding the Right Children's Bike Size:

Your child's bike size is determined by wheel diameter, not frame size.

It's important to choose a bike that's right for their size -- bikes that are too large or small are difficult to control and maneuver. Your child should be able to comfortably sit on the bike with their toes or feet touching the ground, and their knees should never touch the handlebars.

Use your child's height and age as a guideline for finding the best bike:
