10-46 Guitar String Tension in Drop D

Summary

A 10-46 electric guitar set tuned to Drop D (D A D G B E) on a 25.5″ scale produces about 99.2 lbs (45.0 kg) of total tension. Individual strings range from 13.4 lbs (string 6, D2) to 19.0 lbs (string 5, A2). That is about 3% lower than a 10-46 set in E standard on the same scale (102.7 lb).

Total: 99.2 lb (45.0 kg)

Reading the result

• No string deviates from the set median by more than 35%, so the calculator's balance check does not flag this set.
• These are calculated estimates. Real strings vary by manufacturer, so enter your exact gauges in the calculator for a precise figure.

How this was calculated

Each figure uses T = UW × (2LF)² / 386.4, where UW is the string's unit weight in lb/in, L is scale length in inches and F is the pitch in Hz (A4 = 440 Hz). Strings of .020″ or less are treated as plain steel; heavier strings as nickel wound. Manufacturers' gauges differ slightly, so treat the numbers as close estimates.

Accuracy against published D'Addario charts is about 1% for plain and phosphor-bronze strings, 2% for a 10-46 nickel wound set and up to 8% for heavy bass strings. Full sources and validation are on the Methodology page.
