how do i make my rendered image bigger?

when i render my image and save it, its dimensions are quite small (a4 ish), how do i make it bigger?
can someone step by step me through this please?



Yep, just look for this render panel. It’s the button with the Camera icon.

More specifically you want to look at resolution.
Percentage is the percentage of that resolution - useful if you want to render off a quickie at half size, etc.

good stuff, thanks a lot!!
