Bike Frame Measuring Tips

bike frame measuring

It’s actually quite easy to do, and once you know what you’re doing, there’s really not much of a learning curve. You simply need to get a tape measure and a pen or pencil. Hold the bike frame securely with both hands, with the wheelbase at ground level. Make sure the tape measures from the ground up, not just above it.

Read The Measurement Out Loud

The next step in bike frame measuring is to read the measurement out loud. Note the distance between your bike frame’s top bracket to the ground. You don’t need to get a mic or anything like that; just make note of the distance precisely. This measurement will help you gauge the length of your bike frame, as well as the width.

In general, a frame’s height is measured from the ground up. If you’ve ever been shopping for a bike, you’ve probably seen a lot of bikes with short or even very short frames. Usually these are made by ‘screwing’ the post into a wooden frame that’s much shorter than the one you wanted. However, if you have a custom bike, you may be able to have something made specifically for your desired height and length. In any case, bike frame measuring isn’t terribly difficult, but it does take some time.

Move Onto The Next Item

Once you’ve measured your frame, you can move onto the next item on your list-the fork. Fork measuring is fairly straightforward-you simply measure the seat tube of the fork. To measure the bottom bracket, you’ll have to get a different tool, one that’s specifically designed to measure for the bottom bracket.

The handlebars are next on our list of things to measure. The shape of your handlebars will have a significant effect on the overall length of your bike frame. You want to make sure that they’re comfortable, as you’ll be using them for a long time. You’ll also want to make sure that they fit your hands properly, as making them fit poorly could cause pain during your rides.

Check To See How Secure The Frame is

Next, you’ll want to check to see how secure the frame is. Many older models will have little bolts that lock the frame in place, but newer bikes are generally made of a more sturdy material. If your bike frame was made a few years ago, you might not need to worry about it-it’s probably time to replace it. However, if you ride today, you should make sure that the bolts are fully operational and are not rusty. You never know when rust can weaken the bolts on your bike frame.


The last thing that we’ll discuss is what kind of bike frame measuring device you should use. If you want to measure your bike frame with a tape, you can do so with a standard tape measure. There are specialized tools available, however, if you’d prefer to take it indoors. They have longer grips and higher measurements so they can better reach the areas that you need to measure.
