A mountain bike frame size chart is a great tool for anyone who is buying a new bike or replacing an old one. It helps you determine the proper size that will fit your body type. The chart is divided into four categories which are the top, the midrange, the entry-level, and the low level. You can start by consulting the chart and determining the appropriate size that you need. Once you have established this, you can go on to the next steps.

In the chart, you will find the measurement of the legs. It measures from the knee down to the ankles. The height should be taken separately. The next step is to get the height and width of your hips. This data is important for getting the correct size of your mountain bike frame.

The next area in the mountain bike frame size chart is the arms. The measurement here is taken from the elbow to the pectoral muscle. For this part, you will also need to include upper arm measurements. Arm measurements are rounded up to the nearest inch. The height of your shoulders can also be found out from the height of the top of your head.

The next step is to get the length of your torso measured in centimeters. The measurement is taken from the hip to the bottom of the knee. The measurement of your legs can also be found out from the pedals you are riding with. A typical mountain bike frame size chart has bikes of different sizes listed according to both the length and the width of the legs.

Important Parts

When you are ready with the measurements, you can then proceed to decide on the right side of the frame that will fit you. The chart provides you with recommendations on what kind of bike will fit your height. The main recommendation is that you ride a bike that matches your height and riding style; this will ensure that you have maximum comfort while riding and that you will not feel discomfort when riding your bike.

So we have made our height and legs into two categories. Now we need to take the saddle size into account. You will find the seat height on this chart very similar to the height chart. This gives you an idea of what will be the right frame length for you. If you have already bought your bike, then check the handlebars as well for the right height.

The last part is the wheels. This is usually the most confusing part for new riders. There are some manufacturers that have built wheels that are specific to each mountain bike model. The wheels will generally have a bearing that is specifically designed for mountain bikes. You should know that cross country riding requires different wheels than racing.


Mountain bikes come in different sizes, and you need to choose the right one for your needs. It is also important to choose the right frame size. It should fit you well, and you should not feel uncomfortable in it. If you follow these tips, you should have no problems getting your bike frame size.

The other important part of your bike frame size is the seat tube. The seat tube refers to the distance from the head tube to the seat tube. The seat tube will have a large part-shaped lip on it. The seat tube will determine how deep your water bottle can go. Generally, you will want to go with longer tubes if you plan on riding on hard surfaces a lot.

You will need to know how many inches you want from your bike size guide. This measurement will be used to tell you what size of tires you will need. The chart will tell you the tire diameter and the height of the tire. This is all based on the standard fork out on the bike. It may have a small offset on the fork that may vary according to the brand you buy. You will need to do your own research to find out what fork sizes will work best.

Bottom Line

A great way to determine what size of mountain bike frame you need is by looking at the seats. Seats, as they are known, are the items that sit on the top tube of your bike. Usually, most seats will follow the standard sizes for bikes, but if they don’t, you can get custom-made ones that will fit your frame perfectly. This is a great way to save money on your next bike and make sure you get the best fit.
