Measuring trim for mitered baseboard installation

I'm looking to install baseboard trim in my dining room. I have an electric compound miter saw and know how to use it, but my problem comes when I measure the walls to make the appropriate cuts.

For "outside corners": If I measure the wall exactly, cut the trim to that length, then make the mitered cuts on the ends, won't that screw up the length? Do I need to add 1/2 inch to each end when cutting the trim to length to make up for the mitered corners?

This problem doesn't occur when cutting trim for inside corners because you're cutting excess off of the trim so it can fit into the corner, but in an outside corner you need the ends to stick out further than the measured length of the wall.

Maybe I'm just not visualizing this correctly -- spatial intelligence was never my strong suit. If anyone can help, I'd appreciate it!

The first step is to take a rough measurement of the wall, cut you piece about 6 inches too long, then put your measuring tape aside.

With your rough cut piece, cut one side with the cut you want then walk over to your wall and mark where the other cut needs to be made.

It usually is easier to make the inside cut first then mark an outside cut.

For two inside corners its a bit tougher but you'll get the hang of it.

Good advice there. Put the tape measure down and "sneak up on the measurement" a little at a time. Helps to have the saw close.

Your outside corners should be mitered but inside corners should never be mitered. They should be coped. Mitered inside corners just scream "an amateur did this!!!" It isn't hard and it can be done with a $12 coping saw and a little practice. Do a search on youtube for coping baseboard.
