• D'Addario String Tension Pro -- https://www.daddario.com/string-tension-pro/
  • has been down for some time, partially inspiring this work
  • but I remember it being pretty nice
• https://stringtensioncalculator.com/
  • specifically for Kalium strings
  • somewhat similar to D'Addario String Tension Pro (from what I remember)
  • select scale length (0.25" increments), pitch, and gauge -> shows tension and frequency
  • shows 6 (or more) strings at once
  • scale length presets include a few multi-scale options
  • source: https://github.com/aaronabramov/string-tension-calculator
• Shelquist -- https://wahiduddin.net/calc/calc_guitar_tension_from_size.htm
  • input scale length (in | cm), diameter (in | mm), pitch class, octave -> shows tension in lb and kg for several D'Addario steel-core string types
  • lots of info on the page
  • some nice messages if tension is too high or low
• Curt Mangan -- https://www.curtmangan.com/string-tension-calculator/
  • 6, 7, or 8 strings
  • multiple scale length presets, including many multi-scale, but can't set your own
  • (guitar / electric bass focused)
  • standard tuning default, but a selector allows tuning down all strings by 1--4 half steps
  • for each string individually, can change gauge and pitch
  • shows tension plot and sum
• Stringjoy -- https://tension.stringjoy.com/
  • some useful info on the page
  • for Stringjoy strings
  • select string type, # of strings (6--9 | 12), scale length (any float, inches)
  • for each string individually, can change scale length, pitch, gauge
  • shows individual tensions and total tension interactively (i.e. don't need to submit)
• Theo Parmakis -- http://chordgen.rattree.co.uk/tensiontool.php
  • some useful info on the page (« show more information... »)
  • unique feature: offers presets for different instruments, including different tunings
  • reference presets "are mostly based upon my own instruments, and the gauges I usually string them with"
  • once, you find a preset you like, click and can edit
  • for whole set, can change scale length (any float, in | mm), string material, winding material (can't set individually), whether to double all
  • for each string, can change pitch, plain or wound, string material (steel, nylon, gut, Nylgut), gauge, single or double
  • shows tensions for each course and the total
  • unique feature: "equalize" button, defaults to tension on top string but can choose which one you want to equalize to
  • based on the D'Addario data but also extrapolating to some other materials
  • can show tension (lb), string gauge, and frequency (Hz) plots
  • nice text format, e.g. .026 w N @ 25" = 13.165 lb
  • can handle strings starting arbitrarily further up the fretboard (after the @ in the tuning editor)
  • purports to offer the source code, but the link currently (2022-04-15) doesn't work
• https://rodrigocfd.github.io/string-tension-calc/
  • compare multiple string sets using string tensions and a tension plot (though not total tension)
  • electric guitar focused, including a few 7- and 8-string sets
  • after selecting a set, can adjust individual strings (gauge and plain/wound) and pitches (-5--+1 half steps)
  • can also choose to tune down the whole set by up to 4 half steps, like the Curt Mangan app
