Printable glove sizer: a true-size palm ruler, a circumference strip and the EN ISO 21420 chart on one page. Print at 100%, check the 50 mm control bar, then lay the hand on the paper. No printer? The on-screen sizer above measures the same 84.5 mm palm without one.
01 · Universal hand gauge · EN ISO 21420
Print at 100% (actual size), then measure the control bar: it must be exactly 50 mm. Lay the outer edge of the index knuckle on 0 and read the little-finger knuckle; wrap the strip round the palm below the knuckles, thumb out.

Wenaas and Tilsatec reproductions of EN ISO 21420:2020 agree on every value. Flat width = circumference ÷ 2.42 (men’s 50th-percentile ratio).
Golf column uses circumference only (Regular cut); length can move it to Cadet. Goalie: nearest inch + 1 (Keeperstop). Exam gloves: EN size 6/XS … 11/XXL (Shield Scientific).

05 / Field guide
The printable sheet carries a true-size palm ruler, a circumference strip and the EN ISO 21420 chart. Printers often shrink a page to fit the margins, so the sheet has a 50 mm control bar: measure it with a ruler before trusting the rest. If it is not exactly 50 mm, print again at 100% or “actual size”.
Lay the hand flat on the palm ruler with the outer edge of the index knuckle on the zero line and read the little-finger knuckle. Cut out the strip, wrap it round the palm below the knuckles with the thumb out, and read where the end meets the scale: that is the circumference and the EN size.
An 85 mm palm on the ruler is about 206 mm round: size 8.
check: control bar = 50.0 mm circumference ≈ width × 2.42 (men) · 2.41 (women)
The on-screen sizer at the top of this page measures the same hand at true size on a calibrated screen: a phone held sideways, a tablet or a laptop.
Brand cuts differ inside a size: when the sizer lands between two sizes, or on the edge of a band, try both.
A browser does not know how big its pixels are, so the sizer starts from a table of 114 phones, tablets, laptops and monitors matched to your screen’s size and pixel ratio, an estimate good to about five percent. Laying a coin or a bank card on the glass and matching its outline replaces the estimate with a measurement good to a fraction of a percent, saved for this screen only.
Browser zoom is corrected automatically from the pixel ratio; pinch zoom is flagged, because nothing drawn is true size until it is undone.
pixels per mm = CSS px across the card ÷ 85.60 mm ID-1 card: 85.60 × 53.98 mm (ISO/IEC 7810)
For children, the strip is the most reliable tool: small hands are hard to hold flat on a ruler. Rawlings’ batting-glove chart then turns a hand length into a youth size: Youth S at 6–6.25", Youth M 6.25–6.5", Youth L 6.5–6.75", Youth XL 6.75–7" (palm base to middle fingertip).
Keep the printed sheet with the gloves you buy: re-measuring at the start of each season catches the jump from youth to adult sizes, which usually comes between 11 and 13.
If the control bar measures 49 or 51 mm, every reading on the sheet is off by the same 2 percent; print again rather than correcting by hand.
Questions
Choose 100% or “actual size” in the print dialog, not “fit to page”, then check that the control bar measures exactly 50 mm.
Yes: calibrate the screen with a coin or card and use the on-screen 1:1 sizer on this page.
Wrapping round the palm to measure circumference directly, which is the number glove sizes are based on.
No; the sheet fits both and the scale is the same at 100%.
The printer scaled the page. Print again with scaling off (100%), or use the on-screen sizer.
Wrap the paper strip round the palm below the knuckles, thumb out, and read the circumference; for ball and batting gloves measure from the base of the palm to the tip of the middle finger.
Both are true size when set up right: paper when the 50 mm bar checks out, the screen once calibrated with a coin or card. The strip measures circumference directly, which is what glove sizes use.
