Haibike Sduro HardSeven Frame size

[GDW40]

Hi - I’m selling my 2015 Haibike sduro hardseven on eBay and I’m trying to work out the frame size. I can’t see it marked on the frame. Any suggestions where I should look or how to work it out?

thanks!

I think the traditional measurement is top of seat tube to centre of bottom bracket.

Pictures of tape measure held against the frame on the three sides of the triangle are probably a good substitute for knowing what the maker called it!
