THE PRACTICAL PART

More making. Less guesswork.

Useful calculations, together at your workbench.

01 / CLAY RING STUDIO

Foolproof Metal Clay Ring Sizing. No Guesses!

Explore wet, dry, and fired dimensions with the original ring sizing calculator. Includes US / UK sizes and clay-specific firing references.

02 / PLAN YOUR DIMENSIONS

Calculating Shrinkage UP for a Target Dimension (Bezels and Components) Wet and Dry

Enter your finished dimension to find the wet and dry starting sizes.

About these measurements

Uses the same observed ratios as Clay Ring Studio: wet = finished × observed wet ÷ observed fired. Drying and firing compound. Directions are kept separate; the selected observation is an estimate for your piece, not a guaranteed result. Historical measurements are not calibrated to the researched firing schedules.

03 / KEEP YOUR UNITS STRAIGHT

A weight off your mind.

Translate weights for your materials, recipes, and studio notes.

CONVERTED WEIGHT

A troy ounce is 31.1034768 g. A standard ounce is 28.349523125 g. Choose the one your recipe uses.

AT THE DRILL PRESS

Drill/Gauge converter.

Enter a fraction (3/16), mixed number (1 1/8), or decimal (0.1875). Numbered and letter drill designations are not supported.

METRIC SIZE

1 inch = 25.4 mm exactly. Reverse conversion also shows the nearest 1/64-inch increment and its difference from your target; this is a size reference, not a guarantee of drill availability.

Cuff Instructions

This Tool can be used to calculate the make size for any Cuff or Bangle bracelet. Measure the length of the desired cuff or diameter of the bangle with a string or flexible tape measure. Input that linear length into the finished dimension field. Choose your desired clay and the calculator will output your wet make size and the dimensions it should be dried. I usually add about 5% in length for cuffs, just in case. Dry over your chosen form and fire as normal.
