12-52 Guitar String Tension in Eb Standard

Estimated tension per string, 25.5″ scale.

Summary

A 12-52 electric guitar set tuned to Eb Standard (Eb Ab Db Gb Bb Eb) on a 25.5″ scale produces about 128.4 lbs (58.2 kg) of total tension. Individual strings range from 19.3 lbs (string 6, Eb2) to 24.2 lbs (string 4, Db3). That is about 25% higher than a 10-46 set in E standard on the same scale (102.7 lb).

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.
  • Higher overall tension feels stiffer and takes more effort to bend. Check that your nut slots, truss rod and neck are happy with the extra load before committing to a heavier 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.
