How to Measure a Bike Frame

It does not take an expert to figure out the basics of measuring a bike frame. This is one thing that you can do even on your own as long as you follow the steps that are briefly mentioned below.

Start by Knowing your Height

Before anything else, determine your height. This is important because your height will determine the size of the frame that will be most suitable.

Recommended Frame Size Based on Height

Generally, for bikers who are between 5’8” to 6’, an 18-inch frame will be more than enough. If you are shorter, on the other hand, 16-inch frames will be suitable. Meanwhile, if you are taller, you will be good with a 20-inch frame.

Find the Top Seat Tube

When it comes to actually measuring the bike frame, the first thing that you need to locate is the top seat tube. This is the entry point of the seat post or the point at which it attaches to the frame.

Look for the Bottom Bracket

Now that you have located the top seat tube, the next part of the bike that you should be looking for is the bottom bracket. It is cylindrical and is located underneath the seat tube.

Take the Measurements

After locating the two parts, it is now time to take the measurements. Use a tape measure and place one end on the top part of the seat tube. Run it all the way to the center of the bottom bracket. This is now your frame size.

In some bikes, you will no longer need to take the measurements manually since they are already provided by the manufacturer. There are models with stickers on the top of the seat tube to indicate the size of the frame.

Wrap Up

By now, we hope that you already know how to measure a bike frame. It is fairly easy since all that you have to do is to compute the length of the seat tube and the bottom bracket. Once you have the measurements, see to it that it will match your height to guarantee a comfortable ride experience.
