I've been wondering how to do this for a while but I couldn't find anything that gave me answers. I'm trying to make a realistic-ish model but I don't know how to round the edges.

    $\begingroup$ Hello :). Is the Bevel Modifier what you're looking for? Perhaps add an image to illustrate. $\endgroup$ Aug 3, 2020 at 19:20
  • $\begingroup$ It might be. I'm not sure how to add an image though. $\endgroup$

You can use the Bevel tool.

  1. In Edit mode, select all the edges you want to be rounded.
  2. Hit Ctrl+Shift+B to initiate the tool.
  3. Adjust the offset (radius) of the rounded corners by sliding your mouse.
  4. Adjust the number of segments (subdivisions) you want with the mouse wheel. The more there is, the smoother the corner will be.
  5. Validate the operation with a mouse click or by pressing Enter.

You can adjust those parameters, and many others, by expanding the "Last Operator" panel (bottom left of the Viewport; it should be labelled "Bevel"):

I assume you want to round edges of a rectangle, a planar surface; if you want to round the edges of a volume, you should use Ctrl+B instead.
