Crank axle lengths

68/73mm shell, which size axle is needed? Not bottom bracket but crank.
I'm trying to buy a crank for a short person, me, 165mm crank arms.
Sellers do not know what shell they fit or what bike they are from so they have measured the axles they are between 130 and 135mm long.
I'm guessing that is 68/73 rather than boost. Can you even get a boost crank in a 24mm diameter?

How about you give us a clue and tell us what cranks?
You seem thoroughly confused, boost cranks may be no different to non boost (my X0 for example can be used in a 68, a 73, some pressfit and boost or non boost).

I thought boost crank was wider for 83mm shell but I also thought they came in 30mm diameter spec and not 24mm.

boost is just the offset of the chainring for 148mm rear hub you can still get them for 68/73mm bottom bracket widths but i guess newer bikes are more 73mm, 68mm i think is more road bike size.
135mm sounds about right as if you have 73mm width bottom bracket and then the cups will be what 10mm each side, then you have the left non drive side crank arm what 25mm etc.
Just make sure you buy the correct size for your bottom bracket, as already mentioned there is 24mm shimano or 30mm axle diameters.
Yeah I'm running bb70 so needs to be 24mm axle.
Hopefully with get either of them, I have used a chester before, looks nice and performs well, saint might be a bit heavy for xc bike but limited for 165mm cranks in the used market. There are zee cranks but I like to build somewhat pretty bikes and the zee stuff looks like sram nx, a bit boring looking, boring shapes.
There are some GX on the evil bay right now and sometimes X0 come up.
