A 4×4 drawing grid keeps the portrait in proportion.

How do I use this tool?

  1. 1.Choose what the lines will cover

    Upload an image for a photo reference and choose its paper format. Use the blank Grid Generator link if you only need an empty sheet.

  2. 2.Set the horizontal and vertical divisions

    Start with six rows and four columns. Increasing rows adds horizontal divisions; increasing columns adds vertical divisions.

  3. 3.Review the guide at the final shape

    Adjust the line appearance and export the PNG. Check that your chosen grid gives useful reference regions before printing or drawing from it.

Before I download

Can I add just one horizontal or vertical division?

Use one row and two columns for a vertical split, or two rows and one column for a horizontal split. The custom grid supports counts from 1 to 30.

Can I draw diagonal annotations by hand?

No. This page creates regular or preset composition guides. It does not include freehand drawing, arrows, or individually positioned annotation lines.

Rows and columns solve different problems

A tall object may need more horizontal checkpoints than vertical ones. Six rows and four columns provide 24 regions without forcing a square canvas. The cells need not be square, but any drawing copied from this reference must preserve their proportions.

Use measured dimensions only at print time

The page format determines the shape of the digital output, not its final physical dimensions. If you need a specific cell width, divide your intended printed width by the column count, then set and verify the scale in your printing application.
