BARBELL MATHS

the IWF colour code and the plate count: from target weight to each side of the bar, no calculator

Built as a memo rather than a table: the thing worth hanging it up for reads across the room, with the full reference in smaller type below it.

Three sizes in one archive — from a sheet on the fridge to a poster on the wall.

Weights, colours and bars follow the IWF equipment standard; the numbers on the discs are printed with a point, as on the discs themselves. The chart counts plates for one side of the 20 kg bar, without collars.

THE WEIGHT CAN BE READ ACROSS THE GYM

The colours of the standard exist so that the weight can be read from across the gym: a pair of reds on the bar is 70 kg, a pair of blues is 60, and nobody has to count the digits on the discs. A change plate reads the same way, because its colour matches its ten times heavier sibling.

And the full set — one disc of every weight on each side — loads the men’s bar to exactly 185 kg.

On the sheet

  • Weights, colours and bars follow the IWF equipment standard; the numbers on the discs are printed with a point, as on the discs themselves. The chart counts plates for one side of the 20 kg bar, without collars.
  • Colour carries meaning, but meaning never rests on colour alone — the sheet reads in black and white.
  • Nothing about how it was made: the sheet carries only what the reader needs.

Printing

  • Three sizes in the archive: A4 — 210×297 mm, A3 — 297×420 mm, A2 — 420×594 mm.
  • All text is converted to outlines. No fonts to install, and nothing shifts on another machine.
  • White background and sparing fills — it prints on a home printer without draining the cartridge.
  • Margins of at least 10 mm: a home printer cannot print to the edge.
  • No stroke thinner than 0.3 mm, so nothing disappears in print.

Why the numbers can be trusted. Every countable number here is computed from data rather than typed in, and the sheet must pass 8 independent checks before it is allowed to build — how many items there are, the order they come in, and the claim in the highlighted box itself. If one fails, there is no file.
