To assist you with measuring, every company provides its size chart; the following are the bike parts that need measurement:
Tube Lengths
When looking at a bike’s size chart, the top-tube length is usually mentioned in the size chart. It is the distance measured between the tube’s center line and the center line of the seat. Use a spirit level or the clinometer to confirm that your measurement is accurate to get accurate measurements.
Many manufacture scale road bikes based on the length of the top tube. That is not the case with mountain bikes, and they are usually labeled with frame sizes S, M, L, and so on. That’s a strategy that many mountain bike manufacturers utilize.
Seat Length
Seat tube length is the linear distance from the center of the base and the top of the seat tube. Plus, a mountain bike’s seat is frequently curved, so measuring the tube’s path will be longer and more difficult for you.
If you are uncertain about the correct track, straighten the seat’s base and the top of the seat and measure along that line.
Wheelbase
The wheelbase of your bike is the length between the front and back wheels. It’s an essential factor of a bike driving experience, and it varies with a bike’s frame size
It’s straightforward to measure. However, it would help if you pointed the tape straight forward at all costs. If you measure the wheelbase from both ends of the bike, you’ll get more accurate results.
