Knitting stitch planner
Scale a measured knitting swatch into a target rectangle. Rounding to a pattern repeat changes the finished width, which is displayed for you to check.

How it works
Scale a measured knitting swatch into a target rectangle. Rounding to a pattern repeat changes the finished width, which is displayed for you to check. Draw a small bead or pixel pattern and count the colored cells. Download a vector pattern for printing; empty cells do not represent required beads.
Select a country independently of the interface language. Rates and fees are supplied by you unless an official dated source is explicitly stated.

3D print filament estimate
Estimate filament mass and length from solid material volume. Use the sliced material volume rather than the outside volume of a hollow object.
Fabric cutting layout
Arrange rectangular fabric pieces across a fixed roll width. Pieces are not rotated, so you can preserve grain direction; seams must already be included in piece dimensions.
Wall frame arrangement
Place a row of equal frames with equal gaps at the edges and between frames. Check mounting hardware and wall structure before drilling.
Text contrast checker
Check the luminance contrast of a text and background color pair. Passing this check alone does not make a page accessible.
Tiled poster printing
Split one image across several paper sheets for a larger poster. Align the overlap areas after printing and check physical dimensions on a test sheet.
Tempo and practice metronome
Practice at a steady beat and build a gradual tempo ladder. Tap tempo estimates the pace of your taps; browser audio timing can vary by device.
Garden spacing planner
Estimate planting positions in a rectangular bed. Spacing and edge clearance must come from the crop and growing method you intend to use.
Box packing comparison
Compare six uniform orientations for identical rectangular items. The best displayed count is not a proof of globally optimal packing with mixed orientations.
Transpose notes and choose a capo
Move a sequence of pitch names into another key and inspect the fret-zero shapes needed with a capo.
Equal and just tuning comparison
Hear with your own instrument how a chosen pure ratio differs from equal temperament; this tool calculates frequencies and cents, not audio.
Polyrhythm practice grid
Print the shared subdivisions of two rhythms and see exactly where each pulse belongs.
