How it helps
Use it for a focused task
This page combines an interactive counterweight placement calculator with a visual tonearm diagram, cartridge presets, and a printable setup card. Below the calculator you'll find explanations of what happens at different tracking force levels, common mistakes, worn stylus compensation, and a reference table of popular cartridges.
Pick a cartridge preset or enter your own specs: recommended tracking force, cartridge weight, and tonearm effective length. The calculator shows exactly how far from the pivot to position your counterweight, plus the resulting tracking force in grams.
Print or save the summary card. Your last setup is remembered in your browser.
