Bicycle inner tubes come in a range of sizes to fit the width of your tire. You’ll need to know the size of your wheel and tire to select the right tube. Once you have that information, finding the right size is a matter of matching up the numbers.
In this article, we’ll show you how to find bicycle inner tube size so you can get back on the road (or trail) with ease.
- Look at the sidewall of your tire to find your bicycle inner tube size
- The number will look something like “700 x 23c
- If you can’t find it there, you can also check your bike’s owner’s manual
- Another way to determine your bicycle inner tube size is to measure the diameter and width of your tire with a ruler or tape measure
- Once you have those numbers, refer to a chart that will tell you what size inner tube you need based on those dimensions

You can avoid a lot of flats by using the correct size tires and tubes on your bike. But how do you know what size you need? There are a few different ways to figure it out.
The first is to look at the sidewall of your tire. It will have a series of numbers, something like this: 700x23c. The number 700 refers to the diameter of the tire in millimeters, while 23c is the width in centimeters.
You can also find your tire size by measuring its circumference. To do that, simply wrap a tape measure around the widest part of the tire and multiply that number by 2.54 (there are 2.54 centimeters in an inch).
If you don’t have a tape measure handy, there’s another way to determine your tube size.

Once you have those measurements, you can consult a inner tube sizing chart to find the right size.
It’s also important to make sure that you get the right valve type for your inner tube. The most common types are Presta and Schrader valves.
