Mk3 sheets on mk4  

Mk3 sheets on mk4

I notice the bed size is slightly different on the 4, can I still use the textured sheets I have for my 3 on a 4 upgrade, as it will suck if I have to get some more sheets, as I have a few.

From what I can tell the bed sizes are the same 250 x 210 x 210 mm vs 250 x 210 x 220 mm, with the difference being in the height. Looking at pictures it appears that the additional 10mm is gained due to the different extruder design rather than any other change.

I think it's only taller, so the bed size, and therefore print sheets are the same.

There is a note/comment somewhere, that they are compatible.

Looks like the only size change is to the z-axis.

The bed sheets are exactly the same, just relabeled "mk4" if you buy the new ones, so the ones labeled "mk3" can be used with no issues. I've had this confirmed in prusa live chat (I asked a focused question about it)
