How will You Choose the Right Size Bike?

Choosing the right size bike is not so difficult. It requires a few steps to perform when you will decide to choose the perfect size bike for you. You can easily do this if you know some tips and measurement ideas. Here, I will help you to know the whole process of finding out the right bike size for you. I hope, after reading this, you’ll be able to find out the bicycle size that fits you. So, let’s start.

How will You Choose the Right Size Bike

How to Measure The Height of a Bicycle?

If you want to calculate the perfect bike size for you, you have to know first the how bikes are measured. There are various ways to measure a bike size. Different types of measurements are used for different types of bike.

Center to Top Measurement: A common bike measurement way is ‘Center to Top Measurement’. In this measurement procedure, This chart is determined by the length of the seat tube.

Here, the bottom bracket is counted as base or center. Top is the top end of the seat tube where the seat post enters into the seat tube. This method can be used in measuring mountain bikes, road bikes, hybrid bikes etc.

Center to Top Measurement

Center to Center Measurement: Another bike measurement system is ‘Center to Center Measurement’.

In this measurement process, the bike size is measured by the distance between the bottom bracket and the center of the place where the top tube meets the seat tube.

Center to Center Measurement

Top Tube Measurement: In this measurement procedure, the length of the top tube is counted as the size of the bike. This is mainly used to choose right size BMX, but also important in choosing mountain and road bikes.

Stand over Height: In this method, the size of the bike is determined by measuring the distance of the top of the top tube from the ground. It actually says how tall the bike is.

Bicycle Measurements

How to Measure Your Height and Inseam?

Before determining the bike size, you need to know some measurement of your body. At first, you need to measure your total height. You can measure it easily by standing against a wall and marking the wall where it is at the level of the top of your head. The distance between the mark and the ground is your height.

After measuring your height, measure your inseam. With the help of a friend, you can easily measure your inseam.

How to Measure Your Height and Inseam

Measure your torso length and arm length for more convenient result. Torso length is the distance between your crotch and sternum. Arm length is the distance between the end of the collarbone and the middle of the closed fist.

These measurements will help you to find out the right size bike for you.

Learn Some Basic Formulas

You will need to know some basic formula that will help you to determine the right size of your bike. These formulas are developed depending on the measurements that you measured in step 2.

Learn Some Basic Formulas of Stand Over Height

For example- if you want to choose the bike depending on the stand over height, the formula for your comfortable stand over height will be,

Comfortable Stand Over Height = your inseam - 2-3 inches
So, you need to search a bike with a stand over height of your inseam - 2-3 inches

For example, if your inseam is 31”, the calculation of perfect stand over height for your cycle is-

Your comfortable stand over height = 31” – 2” = 29” or 31” – 3” = 28”

So, you need to buy a bike which has a stand over height of 28 inches or 29 inches.

Again, to choose the bike depending on the top tube length, you will need another formula. The top tube refers to the distance of the seat and the handle, so the measurement will depend on your upper body length. The formula for your comfortable top tube length is,

Comfortable Top Tube Length = {(torso length + sleeve length) / 2} - 6
Sum up your torso length and sleeve length in inches, divide it by 2 and subtract 6 inch from the result to get your ideal top tube length.

Let’s think that your torso length is 26” and sleeve length is 28”.

So, the sum of torso length and sleeve length = (26 + 28) = 54 inches

If you divide it by 2, you will get (54 / 2) = 27 inches

So, your ideal top tube length is (27 – 6) = 21 inches.

Otherwise, there are some charts available that will tell you the right frame size for you depending on your total height and inseam height. You can take help from those charts.

Determine What Type of Bike Do You Need?

After finishing your measurement, you need to determine which type of bike you want to buy. There are several types of bikes used for different purposes. For, example road bikes are used to run fast on paved roads where mountain bikes are good for riding in rough terrain.

Depending on the use of different types of bikes and the reason behind buying bike, you need to choose the type of bike you need. A person who buys a bike for cross country ride or race will buy a bike that is a size larger than the regular fit for him. Again, an aggressive mountain bike racer will buy a bike that is a size smaller than the regular fit for him.

Different bikes are measured in different units. For example- road bikes are measured in centimeters. In the case of mountain bike, size is measured in inches.

Try Before Buy (If possible)

The measurement chart that is provided by the manufacturers is not the perfect determiner of the right bike size. Again performing some math by using the formula provided will not find you an exact match bike for you. But these will help you to get a good idea about the size of the bike that will be a close match.

So, before buying, you need to give a try. At first, find out the frame size that is suitable for you by using the charts or performing the math. After getting the size, try bike of that size and some other size that are near the size you have got.

Bike Size

By trying some frame sizes and changing saddle height and some other things, you will definitely find a size that feels right and comfortable to you. So, always try some different sizes before buying the best bike for you.

You should know the above thing when you make a choice for a bike. Otherwise, buying a right size bike will be tough.

What to Do If You Got Your Bike Size Wrong?

Now you have known all the essentials of choosing the right size bike for you. But what will you if you, unfortunately, buy a wrong size bike by mistake? Don’t worry; there is something you can do.

There are two things you can do. The easiest way is selling the wrong size bike and buying a new right size one. But if you don’t want to do it, you can try to make it fit buy re-positioning some parts as follows.

  • check
    If you feel that the bike is too high, make the seat post shorter to create a comfortable position. If the bike seems too low, longer the seat post to get a comfortable position.
  • check
    If you think that the handle is too far from the seat, slide the saddle forward to get a relaxing posture. If the seat and the handle seem too close, take the saddle a little backward to get enjoyable posture.
  • check
    If following number 2 doesn’t make the posture comfortable, you can change the stem and use a shorter or longer one according to your need. You’ll need shorter one if you think that the gap between the handle and the seat is too long. Otherwise, you’ll need the longer stem.

These are the basic things that you can do to make a wrong sized bike fit. If these don’t work, you have to follow the first way.

Expert Advice is Invaluable

Bike experts have some advice on bike size in their writings or interviews. The founder and head bike fitter of Bike Science Andy Sexton advised to ask riders and clubs around to gather information about the best bike fitters.

After that, you have to contact that fitter or those fitters to get the right information about sizing before you buy a bike.

He also advised to search for someone who can suggest you a bike size by using a fitting jig. This is an adjustable fitting bike that helps to determine the right bike size.

After fitting from a bike fitter, you should pay a re-visit to the fitter after a few weeks and tell him how your positional changes have affected you. He said that this will help the fitter to know the impact of change on you and he will be able to help more with your biking experience.
