Hi, im buying a new mountain bike and have seen several I like online. By coincidence the shops im interested in list their bike sizes as xsmall, small, medium, large and xlarge. But in all their sizing guidelines they list the bikes frames sizes in inches, with no mention of sml, med or lrg etc.
Does anyone know what are the size of the frames in inches for each of these XS, S, M , L and XL sizes?
Cheers!

I know this is confusing. It varies by brand. Also, there are at least 3 different methods of measuring frame size. I’ve put some of the best links below to help you educate yourself on frame sizing.
Before you buy, make sure you know exactly how/where your seller is measuring the frame and get them to translate the S M L scheme to inches. Sorry to say that this will vary not only by brand but also by seller. Make sure you get it right, because fit is important. If you have to err at all, err on the small size, as seatpost and stem adjustments can make up for a frame that is on the smallish size.
It’ll vary a little between different makes but in general:
xs 13
s 15
m 17
L 19
XL 21
all depends on the brand but ride some differnet sizes and check the geometry charts on there website
It will definitely differ by brand. For instance, I have an XL Gary Fisher which is the same as a 23" frame (not 21" as reported above). So, there can be rather significant differences between manufacturers. The isn’t a standard measurement.
