Add an accurate grid to any reference photo so you can copy it square by square, the classic grid method artists use to get proportions right. Set the grid by number of squares or by real cm/inch spacing, add diagonals and labels, then print it or save it as PNG or PDF.

How to use the Drawing Grid Maker
Add your reference photo: drop it on the box, paste it, or press Choose photo.
Choose the grid: set the number of columns (rows follow automatically with square cells), or switch to Spacing and enter a square size in cm, inches, pixels or percent.
Style it: add diagonals, labels, and pick a line color that contrasts with the photo. Turn on Grayscale to see values better.
Plan your paper: enter your paper or canvas width to see what square size to draw, or download a matching blank grid.
Download or print the gridded photo as PNG or PDF, then copy it one square at a time.
How to use the grid method
Grid the reference: make the gridded photo here and print it or keep it on a screen next to you.
Grid your paper: draw the same number of columns and rows lightly in pencil (or print the blank grid). Only the square size changes, so the drawing can be larger or smaller than the photo.
Copy square by square: look at where each line enters and leaves a square, and copy that onto the matching square. Labels (A1, B3…) help you keep your place.
Erase the grid once the outlines are in place, then shade and color freely.
Grid size formulas
With the same number of squares on the photo and on your paper, everything scales by one factor:
Square size on paper = drawing width ÷ number of columns.
Rows with square cells = photo height ÷ square size, rounded up (the last row can be partly cut off).
Square size in pixels for a cm grid = square size in cm × photo width in px ÷ printed width in cm.

Tips
Draw the grid lightly with a hard pencil (2H) so it erases cleanly, or use a water-soluble pencil on canvas.
Add diagonals for portraits: they make it easier to place eyes, nose and mouth at the right angles.
Turn on Grayscale to judge light and dark values without being distracted by color.
Use finer squares only where needed: a face can use a smaller grid while the background uses the main one.
Frequently asked questions
What is the grid method in drawing?
The grid method divides a reference photo and your drawing surface into the same number of squares. You then copy the picture one square at a time, paying attention only to the shapes inside each small square. It makes proportions and placement much more accurate and is used by beginners and professional painters and muralists alike.
How many squares should my grid have?
For a portrait or pet on A4 or Letter paper, 6 to 10 columns is a good start. Use more squares for detailed areas or large paintings, and fewer when you are confident. Very small squares make the drawing slower without improving accuracy much.
How do I scale the grid to my paper or canvas?
Keep the same number of columns and rows and change only the square size. This tool divides your paper width by the number of columns: for example, 8 columns on a 24 cm wide drawing gives 3 cm squares. The height needed is the number of rows times that square size.
What are the diagonal lines for?
Diagonals add extra reference lines through each square, so you can place curves and features (eyes, the corner of a mouth, a building edge) more precisely without making the grid finer.
What does the cm or inch spacing option do?
It draws squares of a real-world size based on how wide the picture will be printed. Enter the print width and a spacing, such as 2.5 cm, and the grid lines land exactly 2.5 cm apart when the photo is printed at that width.
Will the grid lines be visible on dark photos?
Pick a line color that contrasts with the picture: white or yellow for dark photos, black or red for light ones. You can also raise the line width, or turn on Grayscale so a colored grid stands out.
Is my photo uploaded?
No. The grid is drawn with the Canvas API in your browser. Your photo never leaves your device.
