Both Domane and Émonda use Trek's numeric sizing (47-62cm). Pick the same size you'd take in any Trek road bike - the size labels are consistent across the range. The big difference is fit: at a 56cm the Domane sits roughly 20mm taller in stack with a slightly shorter reach than the Émonda, so a rider on the edge between two sizes can usually go down on the Domane and up on the Émonda. If your saddle-to-bar drop is already at the limit on a race bike, the Domane in your normal size will feel more comfortable without changing stem length.
Choose the Domane SL 5 if you ride long, rough or mixed-surface roads and want a more upright, compliant position. Choose the Émonda SL 6 if you prioritize climbing, sprinting or a racier fit and mostly ride smooth tarmac.
