A felt road bike size chart gives you a starting point for choosing a frame, but the chart alone won’t guarantee a comfortable ride. In this guide, you’ll learn how to measure yourself, read Felt’s sizing guidance, check the numbers that actually matter, and confirm your fit before you buy or ride. By the end, you should have a frame size you can defend and a short list of adjustments to test.
What a Felt Road Bike Size Chart Actually Tells You
Most felt road bike size charts map your height, and sometimes your inseam, to a frame size listed in centimeters or as a letter code. Felt, like most major road bike brands, uses these charts as a first filter. They reflect how the brand’s frames are typically proportioned for riders of a given height, so they’re useful for narrowing your options.

What a chart doesn’t capture is your individual proportions. Two people who are both 5 feet 8 inches can have very different leg lengths, torso lengths and arm reach. That’s why the chart should be treated as a range to test rather than a final answer.
Why Frame Size Matters More Than Wheel Size
On a road bike, the frame size determines your reach (how far forward you lean to the handlebars) and your stack (how high the handlebars sit relative to the saddle). These two numbers control comfort, power transfer and handling. Wheel size on modern road bikes is largely standardized at 700c, so you don’t need to worry about it when using a size chart.
Step 1: Measure Your Height and Inseam
Start with two measurements. Stand against a wall in socks, feet about 6 inches apart, and mark your height. Then measure your inseam by standing with your back against the wall, placing a book between your legs at crotch height, and measuring from the top of the book to the floor. Use a hardcover book or a level and tape measure for accuracy.
- Height: measure in inches or centimeters, without shoes
- Inseam: measure in centimeters for the closest match to most charts
- Repeat each measurement twice and use the average
Step 2: Read the Felt Size Chart Correctly
Once you have your numbers, find the row that matches your height. Felt’s road frames are typically listed by size designations that correspond to a height range. If you fall between two sizes, don’t guess. Note both options and keep reading, because the next steps will help you decide.
| Your Height (approx.) | Typical Starting Point | What to Check Next |
|---|---|---|
| Under 5’4″ (163 cm) | Smallest frame sizes in the range | Standover and reach, since shorter riders often need a compact geometry |
| 5’4″ to 5’8″ (163–173 cm) | Mid-small to medium frames | Stack height and handlebar drop |
| 5’9″ to 6’0″ (175–183 cm) | Medium to large frames | Top tube length and saddle setback |
| Over 6’0″ (183 cm) | Large to extra-large frames | Seat tube height and frame stiffness |
Use this table only as a rough orientation. Always confirm against the specific model’s geometry chart, since sizing varies between road, endurance and race frames.
Step 3: Check the Geometry Numbers That Matter
Felt publishes geometry charts for each model, usually listing stack, reach, top tube (effective), seat tube, head tube and chainstay length. For most beginners, three numbers do most of the work.
- Effective top tube length: This is the horizontal distance from the saddle to the handlebars. It largely determines how stretched out you feel.
- Stack: The vertical height from the bottom bracket to the top of the head tube. A higher stack means a more upright position.
- Reach: The horizontal distance from the bottom bracket to the head tube. Combined with stack, it tells you how aggressive the position is.
If you are between sizes, a smaller frame with a longer stem often feels more controlled, while a larger frame with a shorter stem can feel more stable on long rides. Riders who prioritize comfort often lean toward the more upright option.
Standover Height Check
Stand over the top tube with both feet flat on the ground. You should have roughly 1 to 2 inches of clearance between yourself and the top tube for a road bike. Less clearance is a safety concern, especially when stopping.
Step 4: Test the Fit Before You Commit
A size chart can’t tell you how a bike feels once you’re on it. Whenever possible, test ride a bike in your shortlisted size at a shop. Pay attention to these areas during the test.
- Hands: relaxed on the hoods with a slight bend in the elbows
- Back: comfortable angle, neither cramped nor overly upright
- Knees: not hitting the top tube at the top of the pedal stroke
- Saddle: you can reach the drops without shifting your hips
If you buy online, check the return policy and plan to make small adjustments. Stem length, saddle position and handlebar width can all be changed without changing the frame.
Step 5: Fine-Tune Your Setup
Once you have a frame size, dial in the setup. Adjust saddle height so your knee has a slight bend (around 25 to 30 degrees) at the bottom of the pedal stroke. Set saddle fore-aft position so your knee sits roughly over the pedal spindle when the crank is horizontal. Small changes here can make a bigger difference than swapping frame sizes.
Common Mistakes to Avoid
- Choosing by height alone. Arm length and torso length can shift your ideal size by a full step.
- Ignoring standover clearance. A frame that fits your height but leaves no room over the top tube can be unsafe.
- Buying the biggest frame you can stretch into. Overreaching strains your back and shoulders.
- Assuming the same size fits every brand. Charts differ between manufacturers, so check the specific geometry numbers.
- Skipping the test ride. Even a perfect chart match can feel wrong if the reach or stack is off for your body.
Tips for Getting It Right the First Time
- Measure yourself in the same clothes and shoes you’d ride in.
- Compare two or three adjacent sizes rather than only the one the chart suggests.
- Ask the shop to fit you on a trainer or with a bike fit tool if they offer one.
- Write down your measurements so you can compare them against future bikes.

Comparing Felt Sizing to Other Brands
If you’re also considering a bike from another manufacturer, the same measurement process applies, but the chart numbers won’t transfer directly. For example, Giant Road Bike Size Chart: How to Find Your Frame Size in 6 Steps and Trek Domane Bike Size Chart: How to Find Your Right Frame Size each follow their own geometry logic. Always compare stack, reach and top tube numbers directly rather than matching size labels.

FAQ
Is a felt road bike size chart accurate for everyone?
It’s a useful starting point but not a guarantee. Arm length, torso length and flexibility all affect the right fit, so use the chart to narrow your options and then confirm with measurements and a test ride.
What if I’m exactly between two sizes?
Compare the stack and reach numbers for both sizes. If you prefer a more upright, comfortable position, choose the larger frame and shorten the stem. If you want a sportier position, the smaller frame with a longer stem often works better.
How much standover clearance do I need on a road bike?
Aim for roughly 1 to 2 inches between you and the top tube when standing over the bike with both feet flat. More clearance is safer, especially for stopping.
Do I need to match my inseam to the chart?
Inseam is a useful cross-check because it relates to saddle height and standover clearance. If your inseam is at the high or low end of a size’s range, pay closer attention to those two measurements.
Can I change the fit after buying?
Yes, within limits. Saddle height, saddle position, stem length and handlebar width can all be adjusted. Frame size cannot, so getting that right first matters most.
Should I size differently for an endurance bike versus a race bike?
Often, yes. Endurance models typically have a taller stack and shorter reach, so riders sometimes choose a size based on those numbers rather than the race geometry chart. Compare the specific model’s geometry before deciding.
When should I get a professional bike fit?
If you ride regularly, have ongoing discomfort in your back, neck, hands or knees, or plan to ride long distances, a professional bike fit is worth considering. Consult a qualified bike fitter or medical professional if pain persists.
Conclusion
A felt road bike size chart is the right place to start, but your final frame size depends on your height, inseam and individual proportions. Measure carefully, compare the stack and reach numbers for adjacent sizes, and confirm with a test ride whenever you can. Small setup adjustments can refine the fit, so don’t feel you have to get everything perfect from the chart alone.
