Height of the saddle and size of the foot

Does the length of the feet affect the saddle height? For example, two people with the same inseam (83cm) but with a different foot size (42 and 45) will have the same saddle height?

A)Height 176cm Inseam 83cm foot size 42
B)Height 176cm Inseam 83cm foot size 45

    There's a bit more to it than that. There's no guarantee that two people with the same inseam would have the same saddle height anyway - regardless of foot size.

    It's only a starting point. set height and adjust until correct for you.

    My suggestion would be to stop worrying about the numbers and start to "feel" your bike fit. That's when you can improve your fit since none else can feel for you. Have the tools with you and do adjustments on an area where you can do hard efforts (or on static trainer, although it might feel different). When going easy you won't notice what needs to be changed to improve comfort/power output.

    I agree with you on setting the saddle height based on the sensations and adjusting it a little at a time. But my question comes from my interest in statistics and from understanding if and how a foot oversized or undersized compared to the height of the person affects the size of the saddle height. Is there any reliable online calculator to set an initial value of saddle height quite truthful? what do you think about wrenchscience?https://www.wrenchscience.com/Secure/Fit/Height.aspx

    It shouldn't affect it because foot length is proportional to leg length and height. There is more info here:

    barring extremes due to injury/abnormality, it's noise level

    there have been several formulae produced to calculate saddle height, of course they give different answers, and they certainly are not science

    dynamic methods are more useful

    I read however in the article in steve it is written that the length of the foot is one of the factors to be taken into account when calculating the saddle height. Also in my case being 177cm tall I have an oversized foot (I have a size 45), the height / length of the foot is usually around 0.15%

    Depends on peddling style. Some people point toes down so saddle can be higher. Some pedal with level feet do saddle will be lower. There is no formula for that unless you have a consistent ankle angle and use trigonometry to calculate additional effective leg length.


    Sometimes. Maybe. Possibly.
