Knowing your height and inseam is important when choosing your bike size. Your inseam is the most important measurement since it dictates things like top tube stand-over height, power transfer, and a comfortable riding experience.

Chances are, you have seen big, confusing geometry charts on bike websites, including ours. When it’s time to pick a frame size, you don’t need to memorize this chart or really even know what most of it means to find the proper bike fit.
Finding the frame size for your height is as easy as knowing how tall you are and a few other measurements. The bike manufacturer and Upway will take care of the rest.

Measurements to know
Unless you are getting a custom bike with the most high-end spec out there, you can skip the professional bike fitting. Fat bikes and cargo bikes might have more flexible bike sizing, while mountain bike and road bike riders will need to dial it in more. Luckily, to get an idea of what bike size you will need, you need to know less than a tailor does about yourself and what a few key bike terms mean.
- Rider height: We often aren’t as tall as we have convinced ourselves we are, so it’s important to double-check and get an accurate measurement so your bike feels perfect in your riding position. When it comes to bike fitting, rider height is not as important as your inseam measurement, though, which determines the distance from the seat to the pedals.
- Standover height: The standover height of a bike is the distance from the ground to the top tube. Ensure that your inseam length is 1-2 inches taller than the standover height of a bike to remain comfortable when standing. Your body should not have contact with the top tube when you are upright.
- Seat tube height: As you might have guessed, the seat tube is the tube with the seat attached to it. It runs from the saddle to the center of the bottom bracket. This tube often features the bike size on it and is a great indicator of your bike size. If a seat tube feels comfortable and you can reach the pedals, keep that seat tube height in mind. Fine-tune the measurement by adjusting the seat height on your own.
How do I know my frame size?
Luckily, the brand will typically tell you your frame size based on rider height and inseam length. They typically provide bike size charts on their website that will provide this information. Upway also has these charts for each brand that offers it. Make sure you don’t just take one brand’s measurement and run with it. Just like clothes, each brand fits a bit differently. Their sizing charts can vary, so be sure to check each one.
Avoid using general bike size charts. They can give you an idea of what bike frame sizes to start looking at if you are shopping in person, but in general, the most accurate measurements will come from the brand’s bike size charts. Each brand has done extensive testing to come up with its size charts based on every measurement available on the bike.

Frequently Asked Questions
What should I measure on myself?
Are sizes the same for all brands?
In general, bike size is similar from brand to brand, but it can vary! Be careful when shopping for different brands and models because your frame size might change, especially if your measurements are on the border of two sizes.
What if my bike doesn’t fit?
If you buy with Upway, this is no big deal. Upway gives customers 14 days to return a bike if they don’t love it. This takes the pressure off when buying, so you can be sure you get the right bike size.
Key Takeaways
- Sizing is easier than it looks: You really won’t need most of that complicated geometry chart. Check out the manufacturer's website for bike size charts and see what they need from you to determine your bike size. Sizing is more sensitive to mountain bikes and performance road bikes.
- Know your best seat tube length: The seat tube length is usually the best indicator of frame size. If you have a bike that fits great, measure the seat tube length so you can be on the lookout for similar-fitting bikes in the future. Know the saddle height, too, and how to adjust it.
- Let Upway help: Upway provides measurements and sizing charts for all of our bikes. We also offer a sizing guide and 14 days of trial riding to make sure your bike fits you properly for the best riding experience.
