How To Choose Road Bike Frame Size – Choosing the right size road bike frame is important for riding comfortably and efficiently. Our bicycle frame size calculator is designed to give you a good starting point for choosing the right frame size for you.
Embers, frame size is not the same for all bike brands and people have different shapes and sizes, so it is always advisable to test the bike before buying.
How To Choose Road Bike Frame Size
– Below the recommended range, consider reducing the frame size, – Above the recommended range, consider increasing the frame size.
Bike Frame Materials Explained
Start by standing with your feet up against a wall. Place a ruler or book as deep into your leg as possible. Now measure from the top of the book/ruler to the floor. Note: You can get better prices if you ask friends to help you.
Most bike manufacturers measure the frame from the center of the bottom bracket (crankshaft) to the top of the seat tube. Most road bikes are measured in centimeters (CM) and mountain bikes are measured in inches (in). (See our mountain bike frame size calculator).
Children’s bikes are measured by the size of their wheels. Smaller wheels allow the child’s legs to reach the circumference and make the bike more maneuverable. However, as the tires get smaller, the ride becomes cramped.
It’s worth taking the time to choose the right frame size for your road bike. Choosing the right frame size will help you feel more comfortable while riding for long periods of time. This improves pedaling efficiency and gives you better control of the bike.

Please note that the road bike frame size calculator and measurement charts below are for guidance only. If you are a serious biker or just like to cycle a lot, you may want to consider getting a proper professional bike from your local bike shop. Here’s an example from a fellow cyclist from the UK in San Francisco
Many say that if your arms are longer than your height, size up and if they are short, size down. However, it is better to leave the leg/seam length. Enter your height in our bike frame size calculator and see what inseam (leg length) it recommends. Then go up or down depending on whether the leg length is closer to a larger or smaller size. In an ideal world you should choose the right frame size instead of going up or down.
Crank length should vary based on frame size, as taller riders have longer legs, meaning longer cranks are more efficient and comfortable. However, most bike manufacturers stick to 170mm cranks for all frame sizes.
Yes, most people should be able to touch the ground with their toes adjusted to the correct riding height. However, it is important to focus on finding the right saddle height for your leg length. You can try our saddle height calculator here to find the correct starting position for your saddle, or adjust the saddle height so that your knees are slightly bent when your feet are at their lowest point.
How To Select The Proper Road Bike Frame Size
Simply put, you don’t want the saddle to be too tight (struggling to reach the bars) or too tight. You also want to stand on top of the pipe while making good contact with the ground. Unless you have a custom-made frame, choosing a frame can be a bit overwhelming, as bike manufacturers can produce hundreds of frames in different sizes.
There are many variables to consider when trying to decide if a bike will fit, starting with reach and stance. Crank height, saddle height and handlebar width (relative to shoulder size) are worth considering.
The best way to find out if your bike is right for you is to start with the frame size calculator (at the top of the page) and then use the saddle height calculator as a base. Then take a test day or rent a bike to see if the size is comfortable. You may want to change the saddle height, stem length and handlebar width to fine tune the bike to suit you.

The Beginner’s Guide To Picking The Perfect Bicycle
All riders are different shapes and sizes. Often, people have slightly shorter arms or legs than average, which makes choosing a frame size difficult.
Also, bike brands can only make a limited range of sizes, meaning their frame size may not fit you. With this in mind, always try to get the leg length (inseam) as close as possible to the recommended frame size range.

For adults, bicycles are classified according to their frame. Visible size is indicated by manufacturers and sellers as the length from the center of the bottom bracket to the top of the seat tube.
Beginner’s Guide To Bike Types
Adult bike sizes are displayed in inches or centimeters and are usually displayed along with a rough size guide such as small or large.
On the other hand, children’s bicycles are classified by size based on the width of their wheels. The size of children’s bicycles is measured in centimeters.
A kid bike can be as large as 24 inches and when your child outgrows the 24 inch bike, you’re ready to ride a grown up bike!
The most suitable bike frame or wheel size depends on the person’s height and inseam. Most bike manufacturers use a one-size-fits-all approach, but bike brand and geometry can change the recommended bike size.

Below I’ll teach you a quick way to measure inseam and length to find the right bike size.
Now that you understand the basics of measuring bikes for adults and children, let me teach you a simple method of measuring a bike.
You need to take two measurements to determine the correct bike size. These measurements are for rider inseam and rider height.
Both of these steps are easier to do if you have a friend to help you. You can pick them up, though don’t worry if you don’t have a helper.
Why You Should Up Size Your Track Bike
I recommend that you take these measurements when wearing the desired cycling shoes. However, if you want to take your measurements with your shoes on, that’s fine.
The inseam is the distance from your groin, the inside of your leg, to the ground.
The inseam measurement determines how long the bike should be so that the rider can reach the ground well when sitting on the bike.
If you wore your normal cycling shoes to measure the inseam, put them back on to measure your height.
Road Bike Size Guide To Help Find A Frame That Fits
To measure a cyclist’s height, you need a sturdy book and a tape measure. A pencil comes in handy if you want to make a clear mark on your wall that you can remove.
Below each bike size chart, I explain how that bike type measures up for frame size.
Manufacturers often display a medium or large rough size next to the frame size to further assist potential buyers.
