Figuring out the right height for a 20 inch bike or for that matter any inch bike can be puzzling.

The wide selection of bike sizes for all height ranges along with the fact that there are wheel sizes as well as frame sizes that you need to take into account make it even more baffling.

But getting the height right is also probably one of the most crucial aspects for a kid if you are planning to purchase one.

The right bike can enhance a kid’s overall biking experience where the kid would look forward to taking the bike out for a spin and have fun with it.

Conversely, the wrong one can lead to a not-so-good experience. Getting the kid to bike and experience the outdoors instead of resorting to sedentary activities is a worthwhile endeavor in itself.

Height Range For 20 Inch Wheel Bike:

A 20-inch wheel bike caters to kids as kid’s bikes are sized based on the diameter of the wheels, unlike adults bikes that refer to frame size as the basis for measurement along with wheels.

A 20 inch bike is ideal for kids who are between 43 and 55 inches tall.

Its a recommended bike size for 6 year olds and 7 year olds.

The best way to go about matching height is by measuring the inseam height of the kid and matching that with the standover height of the bike.

Standover height is the height from the floor to a point on the top tube (the tube that connects the fork in the front to the saddle in the back).

The inseam height of the child has to be a couple of inches taller than the standover height.

A 20 inch bike generally will have a standover height between 19 inches and 20 inches. This can vary slightly between different brands and models.

This is to ensure that the kid would find the bike comfortable and confident with balancing and pedaling.

The next size above is a 24 inch bike for kids who are taller than this height range, and the one below is either an 18 inch or 16 inch bike for shorter kids.

But keep in mind that bigger sizes would weigh more and is also a factor when it comes to getting the right bike for the kid.

So, you’ll have to balance the height requirement and the weight of the bike for the kid’s optimal biking experience.

20 Inch Bike Frame Height:

When the frame size is mentioned, it’s generally a bike for an adult as that’s how adults’ bikes are measured and sized.

A 20 inch frame is generally for an adult who is between 5’10’ and 6’1” tall.

For someone shorter than this height range, you can try a frame size of 18 inches.

Likewise, for very tall adults, a bike that is 21” or 22” in length would be a good fit.

Testing a bike out, if possible, would be recommended as that would help in finding the right fit.

The comfort factor with the bike is ultimately the biggest factor that you should look for.
