Survey: What's Your Height & Frame Size?

Notices
Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Survey: What's Your Height & Frame Size?

Trying to gather some statistics on the range of frame sizes people ride.

Simple questions...

1. How tall are you?
2. How big a road bike frame do you ride? *

* For traditional (level top tube) frames, the seat tube length
* For sloping top tube frames, the top tube length

I'll start:

1. 5'11"
2. 56 cm

Edit: here's the data as of April 19, with 137 entries...



The scatter around the trendline is fairly tight, with a +/- of about 2 cm about the norm.

The trend line formula is:

Frame size (cm) = 0.99 * Rider Height (in) - 13.91

Plugging in my height of 71" gives a frame size of 56.4. Since I ride a 56, it looks like the prediction works for me. How about you?

6'4", 64cm. If I ever buy another bike, I'm going to hunt around until I find a 65.

Both of my current road bikes are 60 cm but were obtained used. If buying new I would probably have chosen 58 cm.

Different manufacturers measure their frames differently. All my bikes have sloping top tubes, except my old 21" Nishiki -- which is a bit big for me.

So: 5' 4" = 74cm leg

My Marinoni Ciclo: 47ST 54TT

My Marinoni Sportivo: 47ST 53TT

My Riv Bleriot (650b): 49ST 52TT

BTW, TT measurements are "virtual."
