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

How do I use this tool?

  1. 1.Load the source image

    Upload one picture and select a paper shape that matches the area you want to inspect. Confirm the image fit before adjusting lines.

  2. 2.Balance photo and grid

    Start with the lighter 6x6 overlay. Increase opacity if the guide is too faint or reduce it when lines conceal an important feature.

  3. 3.Save a flattened copy

    Download the preview as a PNG when the grid is readable. The saved image includes the lines exactly as part of the reference.

Before I download

Can I reposition the grid independently of the image?

The regular grid is aligned to the selected canvas. This tool changes row and column spacing rather than providing a freely draggable grid layer.

Will the download preserve separate image and line layers?

No. It exports one 2400-pixel-wide PNG. Return to the original image if you need to create a different overlay later.

Check contrast in more than one place

A grid that reads well against the sky can disappear over a dark roof. Inspect bright, dark, and detailed regions before choosing a final line color. Lower opacity softens the overlay, while greater line width makes it easier to see at a small display size.

More lines change the reading task

Six rows and six columns create 36 reference cells. That is useful for position checks without dividing every detail into tiny fragments. Reduce the count for a quick composition check, or increase it when you need more precise landmarks for copying.
