Match your height to this model's size range, then confirm stack, reach, and standover on the brand's geometry chart.
Émonda SL 6 size finder
Height gives you one size, or two when the published height ranges overlap. Stack, reach, and standover settle the overlap.
Enter your height and the Émonda SL 6 size that covers it is marked in the tables below.
How to measureHeight gives the starting size. Standover and reach confirm it.
Height ranges
Height ranges for every Émonda SL 6 size, 148 to 199 cm overall. 47: 152 to 158 cm. 50: 158 to 163 cm. 52: 163 to 168 cm. 54: 168 to 174 cm. 56: 174 to 180 cm. 58: 180 to 185 cm. 60: 185 to 190 cm. 62: 190 to 195 cm.
Size chart
Use this as a starting range. Inseam, standover, and how you like to ride still decide the final size.
47
5'0"–5'2"
152–158 cm
Inseam 71–75 cm
Smallest frame. Trek lists this size only down to a 152 cm rider height.
50
5'2"–5'4"
158–163 cm
Inseam 74–77 cm
Reach grows only 5 mm from 47 while stack grows 14 mm, so the front end rises faster than the reach lengthens.
52
5'4"–5'6"
163–168 cm
Inseam 76–79 cm
Between 52 and 54, inseam and standover decide it.
54
5'6"–5'9"
168–174 cm
Inseam 78–82 cm
Most common medium. 54 and 56 meet at 174 cm, so a rider at exactly 174 cm sits on the boundary.
56
5'9"–5'11"
174–180 cm
Inseam 81–85 cm
Longer reach than 54. Take it when 54 feels short, not only because you are taller.
58
5'11"–6'1"
180–185 cm
Inseam 84–87 cm
Check standover clearance before stepping up from 56.
60
6'1"–6'3"
185–190 cm
Inseam 86–90 cm
Reach grows only 3 mm from 58, stack grows 20 mm.
62
6'3"–6'5"
190–195 cm
Inseam 89–92 cm
Largest frame. Highest standover in the range.

If you're 178 cm and fall inside both the 54 and 56 ranges, compare reach and standover rather than assuming the larger size is more comfortable.

Bike size calculator
Enter your height and inseam for a Trek road bike, then compare the result with this Émonda SL 6 chart.
Sizing notes
Riders with the same height can need different sizes because inseam, torso length, flexibility, and preferred handling differ.
3 checks
At the same size label, Trek lists 20-36 mm less stack and 9-17 mm more reach for the Émonda than for the Domane. That means a lower front end and a longer reach to the bars.
Trek publishes both a rider height range and an inseam range for each Émonda size. When the two point at different sizes, inseam and standover usually decide it.
Choose Émonda for the lower, longer position and Domane when you want a higher front end at the same size label.

Questions
Short answers for Trek Émonda SL 6 sizing.
Start from the height range for your measurement, then check inseam and standover for that size. Trek lists both, and they do not always point at the same frame.
No. At the same size label the Émonda has 20-36 mm less stack and 9-17 mm more reach than the Domane, so it puts you lower at the front and further over the bars.
Eight: 47, 50, 52, 54, 56, 58, 60, and 62 cm. Trek lists 47 as the smallest and 62 as the largest.
