I have used many spoke calculators and none of them have my rims.
Measure them yourself. Do that even if the calculator has your rims because rims vary (they get thicker as the extruder dies wear), nipples vary, and people measure differently.

Take two spokes. Measure their length. Insert them into opposite holes on the rim and thread nipples to your target depth (typically the slot bottom). Measure across the elbows with calipers. Add the total spoke length to your measurement to get ERD.

Do it again 90 degrees away. If that varies do the two diagonals. Average.

That's your ERD.
