Full Answer

For mountain bikes, measure the distance from the center of the crank to the top of the seat tube. Measure European road bikes using the distance from the center of the crank to the center of the intersection of the seat tube and the rest of the frame. BMX bikes are measured by the top tube only. Children's bike sizes are measured in wheel diameter instead of frame size.

Measuring the bike frame can help determine if the bike is a proper fit. Bike sizing guides are available, and they vary between road bikes, mountain bikes and children's bicycles. In order to figure out what size frame is right for you, record your height and inseam length; inseam is the more important of the two. You can also visit a local bike shop for help with measurements and testing. If you have your desired bike on hand, stand over the frame, adjust the seat height and level, and adjust the handlebars to find out if you can create a comfortable configuration.

  • Q:

    How do you determine a bike size for kids?

    A:

    Determining the proper size bike for a child is based on the size of the bike's wheels as opposed to determining size for adults, which is typically measured using the frame. Unless a child is unusually tall or short for his or her age, there are standards for every age beginning from the age of 2. Once the basic size is determined, then other amenities can be selected, such as number of speeds, types and shape of the handle bars, types of seats and how the brakes work.

    How do you determine what size bike frame you need?

    A:

    For precise data on the right size bike frame, use the Bicycle Frame Size Calculator by eBicycles. This tool takes the gender, height and leg length of the rider and suggests specific measurements for the size of the bike frame and crank. A quick way to determine the right size bike frame is by measuring the length of the inseam of your leg and choosing a bicycle frame with a “stand over height” measurement at least 1 inch shorter.

  • Q:

    What is the correct bike size for your height?

    A:

    Bike fitting charts suggest frame sizes based on both a person's height and inseam length. To find the correct bike size for one's height, one starts with his inseam length. Inseam length is the distance from one's crotch, where the bike's seat rests, to one's foot.
