Setting Delay to tempo of song?

Hi guys, I've watched a few videos where people recommend setting delay times based on the BPM of your song. How exactly do I find the BPM of my songs in Reaper? Thanks in advance. -Lewis

hover your mouse pointer over the TEMPO indicator in the TCP and you will see a "Tap for tempo" pad, tap the mouse to the beat to find the tempo

Or use a metronome for all recordings! I guess that to make the best of several functions (e.g. the new notation editor) some of us will have to get used to playing to a click.

Or if you're on a known fixed tempo, use ReDelay and set the 'musical delay' as you wish (1/8th, 16th notes etc) ...

Even if I've recorded to a metronome, I still prefer dialling in delay time by ear. Even if you are shooting for perfection, you won't quite get there, and this helps the delay to stick out because it is not hitting the exact metronomic beats and being subject to frequency masking so much. You can also hit upon some really interesting rhythms that you may not have thought of by picking a straight or triplet division from a drop-down list.

Good advice:)
