Bicycle size chart for Felt

Equivalency by height and inseam

To know which size of Felt bicycle you need, the most accurate way is to combine your height with your inseam measurement. This allows you to calculate the ideal seat tube length and choose the frame that best suits you.

Size chart in cm and inches (S, M, L, XL...)

Below, you can check a guideline chart with the recommended sizes according to your measurements. Remember, there may be small variations depending on the geometry and brand of the bicycle.

Height (cm)	Inseam (cm)	Frame Size (cm)	Standard Size	Size in Inches
150 – 160	65 – 70	47 – 49	XS	18.5” – 19.3”
160 – 170	70 – 75	50 – 52	S	19.6” – 20.4”
170 – 175	76 – 80	53 – 54	M	20.8” – 21.2”
176 – 182	80 – 85	55 – 56	L	21.6” – 22.0”
183 – 190	85 – 90	57 – 59	XL	22.4” – 23.2”
190+	90+	60 – 62	XXL	23.6” – 24.4”

How to calculate your ideal size with a formula

If you don't want to rely solely on a chart, you can calculate your Felt bicycle size using a simple formula based on your inseam length. You only need a measuring tape and to follow these steps:

Step 1: measure your inseam

Stand barefoot against the wall, with your legs straight and about 15 cm apart. Use a book or level between your legs, simulating a saddle, and measure from the floor to the superior part of the book. That is your inseam in centimeters.

Step 2: apply the formula

Once you have the measurement, multiply that number by 0.66 to get the ideal frame size (in cm):

Frame size (cm) = Inseam (cm) × 0.66

Practical example

If your inseam measures 78 cm:

78 × 0.66 = 51.48

The recommended size would be a frame of approximately 51-52 cm, equivalent to a size S or M depending on the range of bicycles Specialized.

What if you are between two sizes?

If the calculation gives you an intermediate value, take your riding style into account: for more comfort, choose the larger size; if you want a more aggressive and sporty ride, pick the smaller one.

Frequently asked questions

Not exactly. Although they may seem similar, the geometry and use are different. A size M on a road bike does not always correspond to an M on a gravel or MTB. That’s why it’s important to consult the specific charts for each type of bike.

Yes. The shape and geometry of the frame (aero, endurance, compact, sloping, etc.) can make two bikes with the same “official” size feel very different. It’s always recommended to check the geometry and reach of the specific model you’re going to buy.

Relying only on height without measuring your inseam.
Choosing by intuition without consulting charts or formulas.
Settling for a size just because “it’s the one available.”
Not considering the use: comfort and type of routes also matter.
Ignoring the possibility of adjusting components (stem, seatpost, etc.) if you’re between two sizes.
