How to Read and Verify the Pattern Repeat Calculator Output

The output panel reports the exact result derived from Canvas width, Canvas height, Repeat width alongside any unit or formatting notes.

The result is the full repeat counts and centered leftover margins. Check how many complete rectangular repeats fit on a canvas.

Only whole grid repeats fit; the tool does not rotate motifs or solve irregular packing layouts.

Numerical output shows up to 12 significant digits. Floating-point arithmetic and display rounding can affect the last digits.

Example input
Canvas width = 100; Canvas height = 70; Repeat width = 30; Repeat height = 20
Example output
Full repeats: 3 × 3 Horizontal margin per edge: 5 Vertical margin per edge: 5
