@ Andy Eunson is you 690 from pedal to saddle or centre BB to saddle? Frame manufacturers use centre BB as that way the crank length is irrelevant.
My 5'9"/ 175 cm wife runs a seat height of 695 mm on a medium frame. This is centre BB to top of saddle (and forced to run a 125 mm dropper rather than 150 mm due to seat tube insert limitations and hitting that total length including seat post and saddle stack height - separate story).
I am 6'2"/ 188 cm and I am 795 mm centre BB to top of saddle.
800 mm for XL/ L; 700 mm for L/ M do seem to be appropriate saddle height estimates for determining dropper size choice and effective STA.
Most frame/ bike manufacturers seem to be referencing distance from centre BB to the top of the seat post as they cannot aim off for the wide variety in saddle stack heights (and saddle manufacturers should start to publish this)
