What Size Bike Do I Need? A Complete Bike Sizing Chart Guide

Riding a bike, the most significant thing is to find the right size. With the perfect fit, you pedal with ease, and place less strain on your knees, which enables you to make longer rides. Beginning with your first bike or upgrading your current one, this bike size guide will make you grasp the idea of bike length for height in relation to height and the process of choosing the optimal frame.

The bike size chart is used to clarify the height and cycle size of the adult and kid and how to measure the right frame. You will also understand the effect of the bike sizes in terms of balance and comfort, and how to determine the perfect fit to ride on a day-to-day basis.

How to Measure Bike Size

The most convenient way of knowing the size is to measure the frame of the bike. Locate the seat tube - the straight bar connecting the seat and the pedals. Spin the crank and measure the distance between the center of the crank and the top of the seat tube. That is your bike frame size in centimeters or inches.

Such bike measurements for height  provide you with a clue of what frame fits your body. Nevertheless, in case of doubt, take a bike frame size chart or a racing bicycle size chart of your bike brand and compare the models.

How Do You Figure Out Your Bike Size?

The problem with bike sizing is that it does not have a universal system that fits all bikes and all styles. There are bikes that are measured in frame height (centimeters or inches) and others that are just simple, such as Small, Medium and Large.

You have to verify your height and inseam measurement (how far you are below your crotch to the ground). They both assist in determining the bike frame size - the section of the bike that defines your reach and extension of your legs.

Here's a simple guide:

1. In adult bikes, frame size is used to determine the size of the bike.
2. The kids' bikes are categorized based on wheel diameter.

To be on the safe side, this bike size chart by height will help to provide you with a good point of departure before you even put a bike to the test.

Adults vs. Kids Bike Sizing

Bikes aimed at adults emphasize on the meaning of frame size, whereas kid bikes emphasize on the wheel size.

In the case of adults, frame size influences stability, comfort, and reach. The big frame can make your arms too wide and the smaller frame can be too confined.

In the case of kids, the size of the wheel (12, 16, 20, 24) allows them to have an appropriate fit to the bike according to their leg length and balance levels. The majority of children below 12 years old ride bicycles that are classified as bikes based on the size of the wheel but taller adolescents can ride small adult bikes.

Men’s and Women’s Bike Sizing

Although there are brands that sell bikes with a label of men or women, there is no significant difference in the real dimension. They both refer to the same bike frame size chart.

The key distinction is the comfort adjustments - the models of women can have a shorter reach, another seat, or thinner handlebars. Nevertheless, the right fit based on height will be relatively similar regardless of gender.

Road Bike Size Chart

The road frame size chart bikes are designed to be fast and efficient and hence size plays a vital role. They commonly are judged in centimeters, which is the length of the frame seat tube. The right fit enables you to get to the handle bars without straining your legs.

Mountain Bike Size Chart

Mountain bikes provide inches or size labels (S, M, L). They are less stable and are more relaxed in their geometry.

Note: In case of frequent trail riding, a smaller frame will be more suitable. When you ride long distances, a bigger one will help to diminish fatigue.

Kids Bike Size Chart

Bikes with kids are simpler to size as they are determined by wheel diameter and not frame. The following is the general bike size for height of children:

Tip: In case a child is in a middle range between sizes, use the smaller wheel - it is simpler to manage and will increase confidence.

How to Measure Bike Size

The only way to measure a bike frame is by finding the seed tube, which is the straight tube running up and down the bike frame through the crank (pedal area) to the seat post. Measure centre of the crank to top of the seat tube. The  frame size is that length (in cm or inches).

Also check:

1. Standover height - when standing on your flat feet there must be 1-2 inches clearance between your top tube and your body.
2. Leg extension - the bottoms of your strokes at the pedals should be slightly bent.
3. Reach - you must lean forwards without overstretching.
