Drawing with the grid method

  1. Choose a square size. Big squares are easier for beginners; small squares copy detailed pictures more accurately.
  2. Print both pages. With Fill the page, the blank squares are bigger than the reference ones, so your drawing comes out larger; the note under the grid says by how much.
  3. Copy one square at a time. Find B3 on both pages, look only at where the lines cross that square's edges, and draw just that.
  4. Rub out the grid when you are done, so draw over it lightly with a soft pencil.

The options

A name in every square helps younger children keep their place. Diagonals check angles and the middles of shapes. White lines, which get a dark edge, show up on dark photos; red stands out on black-and-white ones. Black and white and Lighten save ink and make the grid easier to see.

Printing at true size

A4 is 210 × 297 mm and US Letter 8.5 × 11 inches. The squares are drawn at their real size, so print at 100% or “Actual size”, not “Fit to page”, and measure one square with a ruler to check.

Questions

What square size should I use?

For a first try, 2.5 to 3 cm (about an inch) keeps the number of squares small. For a detailed portrait, 1 to 1.5 cm gives more reference points. Younger children do best with fewer, bigger squares.

How do I copy a picture onto a big poster?

Print the reference page, then rule a grid with the same number of rows and columns on the poster, say 5 cm squares. Copy square by square as usual; the drawing grows in proportion.

Is my picture uploaded?

No. It is resized and placed under the grid by your own browser, and it is never sent anywhere or saved.
