For Pre-Master Mixes

Target -18 to -14 LUFS integrated for your mix before sending to mastering. Leave at least 6 dB of headroom (true peaks below -3 dBTP). If your mix is already at -8 LUFS, you've essentially mastered it — and the mastering engineer can't add punch that isn't there.

Red flag: If your mix is louder than -10 LUFS integrated, you're squashing dynamics. The mastering engineer can't undo what your limiter already crushed.
