What Size Bike Do I Need For My Height?

Height is the most important factor for helping you decide your exact bike size. The taller you are, the bigger size bike you’ll want to have.

In order to decide what size bike you need, you’ll first need to know what type of bike you are looking to purchase. Each type of bike slightly differs in size.

For example, mountain bikes are typically more rugged with larger tires and road bikes are more lightweight with narrow tires.

Once you know what type of bike you are looking for, calculating the rest is easy.

If you’re browsing in stores, the best way to tell what size bike is best for height is by standing over the middle of the top frame.

You’ll want to make sure that there is a comfortable amount of space between you and the bike.

For road bikes, about 1-2” should be enough space and for mountain bikes, a little more space, about 2-4”, will work best.

Also, make sure to remember that you can always make some small adjustments to make the bike fit your needs even better.

If you aren’t able to test the bikes out in-store, another great way to find the right bike size for your height is by using a bike calculator.

What Size Bike Do I Need For My Kid?

Finding the right-sized bike for a kid is a bit different than sizing a bike for an adult.

Kids bikes are typically sized by the diameter of their wheels. The wheel measurements for a kids bike is usually between 12-24”.

Any bigger than this and your child is ready for an adult size bike. 

While many kids’ bikes are classified by age, this is not always an accurate way to decide what size bike is best for your kid.

There is a lot of variation in height when it comes to children, so the best way to find the right bike size is to calculate their height and inseam, then compare it with a size chart. 

If you’re able to browse bikes in-store, the standover test is another great option.

For a kids’ bike, the main way to make sure that the bike is the right size is to have their inseam be at least as tall as the top of the bike frame.

What Size Bike Do I Need For a 6 Year Old?

Learning to ride a bike is a pivotal point in the development of any child’s motor skills. At 6 years old, the average youngster is just learning to ride.

You’ll want to make that experience as comfortable as possible to minimize injury and encourage a positive and rewarding experience.   

What size bike do I need for a 6 year old? A 16” wheel will work for most 6-year-olds up to 4 feet tall. However, if your little buddy is a little taller, there’s a chance you may want to consider the next size up. 

Kids come in all shapes and sizes so the best way to get a good fit is a test drive. Go to the store, pick a likely suspect, and help your child step on.

Both feet should be flat on the ground allowing for a bit of a gap when standing. 

Comfort is the key. When seated with feet on vertical peddles, if your child is using their tippy toes to make contact, it may require a simple seat adjustment.

Next, take a look at how they manage the handles. If they have to reach to far you may want to consider the next size down.  

What size bike do I need for a 7-year-old?

What size bike do I need for a 7 year old? Though different factors will play into the size bike you will choose for your seven-year-old, the bike will fall in the 16-inch to 20-inch range. You also have to consider the measurement of their inseam to ensure that the bike size you choose for your child will be safe for them to ride on.

If a child is age seven and has an inseam anywhere from 18 – 22 inches by 45-55 cm, the range most normal seven-year-olds will fit into, a bike size of 16-inches is the appropriate size.

However, if your child is on the smaller side by quite a bit, you can go for a 14-inch, but keep in mind that if they are close to an 18-inch inseam, you will likely have to buy a bigger bike earlier.

If your child is taller for their age or at the 20-22 inch inseam range, you are OK to opt for the 18-inch bike.

This can be safely ridden by a child starting at a 20-inch inseam. Following that vein, if a child is pushing close to that 24-inch inseam, you are safe to go up to the 20-inch bike.

What Size Bike Do I Need For A 10 Year Old?

As your child gets older, it’s understandable that finding the right size bike may be a bit more tricky. 10-year-olds are usually on the cusp between needing a kids bike and the smallest adult-sized bike.

What size bike do I need for a 10 year old? If you’re looking at places that sell bikes, you’ll likely see 24” as the standard size for this age, however, that may not always be the case for your child. At this age, your child may be ready for a larger bike, but they may also like to stay at a smaller bike size as well.

This is a very common situation for this age.

Like with any bike, you’ll never want to base the bike size on the child’s age.

The best way to find the right bike size is always going to be by calculating the child’s height and leg inseam, then comparing it to a size chart.

When available, trying the bike before you buy it is always a great choice as well.

What Size Bike Do I Need If I Am 5’2?

You can determine the size by taking the inseam and height into account for this. Forget just standing near a bike and guessing; the best-sized bike can be picked by focusing on measurement.

What size bike do I need if I am 5´2”? A bike rider that is 5’2 inches tall will want to look at bikes with a frame size anywhere from 49 cm to 50 cm. However, If your height comes more from your legs, looking at the 50 cm frame will be more likely to be the right fit.

The best thing to remember is that you have to be able to ride the bike safely. If you sit on a bike and can not reach the ground, look into why.

The best way to determine if it should be on the lower or higher end of the scale is to try out the bike. If that is not possible, then look at your body type.

If you have a longer torso, you will want to err on the side of the shorter frame.

Can you lower the seat? Is it an adjustable angle? If everything is as low as it can go and you can’t touch the ground, the bike is not safe to ride. Go down to the 49 cm at that point.

What Size Bike Do I Need If I am 5´4?

What size bike do I need if I am 5´4”? At 5’4” a 24’” to 26” wheel works great. Frame height is the standard of measure for adult bikes, so the first thing to consider is age and ability. The 24” wheel is generally considered the last stop for kids bikes, but there are plenty available for adults as well.

The best fit is an individual fit, so consider these important factors when trying the next bike on for size.

Center Bar Height

Straddle the center bar with both feet flat on the ground, you’ll want about 1 or 2 inches of a gap for comfort. 

Seat Position 

Usually, this is a setting that can easily be adjusted. With the pedals in a vertical position, make contact with both feet. If you are overextending to reach the pedal consider an adjustment or a smaller size.

Handle Bar Reach

Both hands on the wheel now, get those paws on the grips. If it’s uncomfortable, and you are reaching too far, look to something a little smaller. 

There’s no substitute for comfort. If your bike isn’t comfortable, chances are, you won’t want to ride it.

So, before you purchase your next set of wheels, try a few out and get to know what fits you best.

Bize Size Guide: 7 Easy Ways to Finding The Right Bike Size

How to Find The Right Size Bike

If you want to choose the right bike size, just follow one of the 7 methods we have found for you:

Method #1: Use a Simple Bike Size For Height Chart

Simple bike size for height can be found in pretty much every corner of the internet. But, to make your search for the perfect bicycle easier, you can take a look at our one below:

Your HeightThe Best Bike Size For You

5ft7 to 5ft1116 inches to 17 inches
6ft to 6ft217 inches to 19 inches
6ft2 to 6ft419 inches to 21 inches

Bike Size For Height

It is worth noting that these sizes won’t apply to every manufacturer (as annoying as we know this is!). Think of it this way — a size medium in Topshop isn’t the same as a medium in Primark, right?

Exactly! You will need to look out for that variation when you are bike shopping.

For those of you who want a little more detail in your size chart but aren’t a fan of the “advanced” ones, the following table is the one for you:

88 cm59 cm20 inches to 21 inches
89 cm60 cm20 inches to 21 inches
90 cm62 cm22 inches

Method #2: Figure Out the Size of the Bike

We understand that not everyone wants to stare at a chart and try to figure the bike sizes out. So, instead, you can do some calculations. Just follow the steps below to work it out.

Step One: Measure Your Leg

Okay, we don’t mean your entire foot to hip leg. Instead, you need to measure your leg’s inseam.

Firstly, take your shoes off. Then, stand with your legs apart. You need to aim to have them 6 inches to 8 inches apart (around 15 cm to 20 cm).

After that, you can measure the height from your crotch to the ground. 

Step Two: Figure Out the Type of Bike You Want

Decide whether you want a mountain bike, road bike, or a city bike.

Mountain bikes are most commonly used for the average cyclist. They are meant to be used over rough terrain like forests etc. Contrary to popular belief, they are different in a lot of ways (more than just the tires).

These bikes have more suspension on the forks, heavy-duty wheels, and so much more.

Road bikes are very special. They are only used when riding on the tarmac and are far too fragile for anything else. They are fantastic for speed, aerodynamic positions, and lightness.

City bikes, on the other hand, are far better for the city roads. You get lights, fenders, chain guard, bicycle stand, and a rear rack with these guys.

They have between 1 and a whopping 27 gears. But you will definitely pay for that.

Step Three: Calculate the Right Bike Size For You

As you may imagine, there are different calculations depending on the type of bike you want to purchase. Let’s take a look at the calculations.

For City Bikes:

Multiply your leg seam measurement in centimeters by 0.685. This equals your correct frame size.

For Mountain Bikes:

Multiply your leg seam measurement in centimeters by 0.66. This equals your correct frame size for a mountain bike.

For Road Bikes:

Multiply your leg seam measurement in centimeters by 0.7. This equals your correct frame size for a road bike.

Method #3: Advanced Bike Size Chart

Yes, we have already looked at a simple bike size guide. But, if you are getting more into cycling, you might want to start consulting the following specific charts depending on the type of bike you are looking to buy.

Method #4: Use a Bike Fit Calculator

Bike fit calculators are, to put it bluntly, amazing. There are plenty of them available online but we’re going to go over one of the most in-depth ones here (and another super well-known fit calculator later).

Step One: Get Your Bike Size Recommendation

The first thing these calculators ask you to do is to measure yourself in loads of different ways. It will take a little bit of time but it’s definitely worth it in the end.

The measurements you need to take are as follows:

?Your height (floor to head)

? Your collar bone to the floor

? Your crotch to the floor

? Your thigh

? Your armpit to the middle of your palm

? Your shoulder to your eye

? Your foot

Then, you’ll be asked to select the type of bike you want to buy and click calculate to get your results.

Step Two: Enter Your Preferred Setup

If you already have a bicycle that you are 100% comfortable riding, you can use this space to input all the measurements of your current bike.

You will need to enter the following measurements:

? The length of the rider compartment (i.e. middle of saddle to handlebars)

? The saddle over bar height

? The angle of the seat tube

? The saddle height

? The seat post setback

? The crankarm length

Step Three: Bicycle Geometry

If you have your heart and eyes set on a particular new bike, you can fill in this section of the calculator to bring up your bike geometry results.

For those of you who know the size, year, brand, and model of your preferred bike, then you can import all the measurements with one click.

Otherwise, you will have to input the following one-by-one:

✔️ The seat tube length

✔️ The seat tube angle

✔️ The height of the lower stack

✔️ The height of the upper stack

✔️ The head tube length

✔️The head tube angle

✔️ The fork rake

✔️ The fork length

✔️ The diameter of the front and rear wheel

✔️ The length of the chainstay

✔️ The top tube length

✔️ The bottom bracket drop

Step Four: Stem, Seat Post, and Headset Spacer

Once you have gone through the former sections, you are provided with the proper stem, headset spacer, and seat post measurements for you.

They will tell you the following bits of information:

? The stem angle

? The stem clamp height

? The stem outer diameter

? The stem length

? The height of the headset spacer

? The seat post setback

? The saddle seat tube top

? The height of the saddle

Bike Size Calculator: Which One Should I Use?

There are a few different methods you can use when it comes to calculating the exact size bike you need.

The easiest is to use a bike/height chart that lists ranges of heights to ranges of bike sizes.

This method only provides an estimate, however, so if you’re looking for an exact measurement you’ll need to do some measuring yourself.

For a more detailed calculation, you’ll want to measure your leg inseam (inside leg measurement). To do this, simply stand with your feet about shoulder length apart and measure in cm from the ground to your crotch.

Then take that number and multiply it by the number for the type of bike you are looking to purchase.

For average city bikes, multiply your leg inseam by 0.685. For road bikes, the inseam should be multiplied by 0.70, and for mountain bikes multiply by 0.66. Upon doing this, you should be able to know your exact bike size height.

If doing math isn’t your thing, you can also look at other online bike size charts.

If you’re still hesitant after trying all these methods, it’s always a good idea to go in person and ask for a bike specialist’s help.

Method #5: Use The Amazon Fit Guide

These days, it’s likely that you’re going to buy a bike online. Probably on Amazon. Are we right? We thought so! Thankfully, Amazon has put together their own adult bike sizing charts for you to use.

For your convenience, you can take a sneak peek at one of them here. The company has made one for road bikes and one for mountain bikes.

Getting a professional bike fit is a sure-fire way to ensure your bicycle is set up perfectly.

The experts are trained to take your proper measurements and help you choose the right bike for you.

Not only do they take all of the above into consideration, but they also think about your style, goals, flexibility, and strength.

Yep, nothing could be more personal than getting yourself an expert bike fit.

Bike Frame Size: What To Consider?

The bike frame size is second only to deciding what type of bike you want to purchase. The kind of bike will also slightly affect the frame size you are looking at, so keep that in mind.

There are a few things to consider when choosing your bike frame size. First, you are going to have to decide what kind of bike you are buying.

Hybrid and Mountain bike frame sizes will vary slightly. Once you have decided what type of bike you are getting, you will then go into how to choose the right frame size for that kind of bike.

Measure, measure, measure. This point can not be overstated.

You will want to consider your height as well as your inseam. Remember, when you are taking your inseam measurement, do not just use one of your pants.

The more precise you are in your sizes, the better the fit of your bike will be.

The best way to measure your inseam is to stand straight with your back against the wall. Then spread your legs anywhere from six to eight inches apart.

Put a book between your legs, spine up, and against the wall. Put it snug against you to imitate the seat of your bike.

Have someone measure the length from the floor to the top of that book.

That is your inseam for your bike.

Keep in mind that it may also benefit you to measure your arm length and your torso height to pick the best bike frame for you.

Measuring your arm should be from the center of the palm to your collarbone.

For your torso, measure from the bottom of the v type bone at the top of your sternum down to your groin.

Bike Size Chart: What To Consider

A good bike sizing chart can come in real handy when making the best purchase decision. Buying bikes online is becoming more popular every day.

Remember to use the chart as a guide. So, even if you are making an online purchase, it may help to pay a visit to your local bike store to get an idea for the size that works for you.

At the end of the day, it won’t matter what the chart says if you aren’t comfortable. 

The two biggest considerations with any sizing chart are age and height.

Another thing that comes in handy when making an online purchase is the rider’s inseam.

This gives you a good idea of reach. For most children under five, balance bikes and tricycles are a great introduction to bikes but some kids get started pedaling early so choose the frame to fit the rider.

Kids grow up fast and it may be tempting to buy a bike that your child can “grow with.” Focus on making the bike riding experience easy and enjoyable.

The same thing applies for adults, If the bike is hard to ride, it will most likely end up collecting dust in the shed.
