Inset not even, even with object scaled in object mode I'm scaling my rectangle in object mode as suggested, and then insetting two faces in edit mode. Yet the inset is still uneven. I can only guess it's because I'm using decimals. I'm scaling thus:
x: 2.92
y: 6.2
z: 0.35

If it really isn't possible to inset this evenly, what are the alternatives to getting an accurate inset?
After scaling in object mode.
