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

How do I use this tool?

  1. 1.Review the diagonal preset

    The square canvas starts with a six-by-six grid and corner-to-corner diagonals. Add a photo if you need a composition reference.

  2. 2.Compare guide structures

    Switch to Custom for only rectangular cells, or inspect the other available guide types before choosing the one you need.

  3. 3.Refine the visible lines

    Set color, opacity, and width so the guide supports the source. Download the selected design as a flattened PNG.

Before I download

Why does the starting grid have diagonal lines?

This page begins in Diagonal mode, which adds corner-to-corner guides to the regular divisions. Select Custom to remove them.

Can this design a responsive website grid?

No. It creates visual image guides. It does not generate CSS, breakpoint rules, or website layout code.

Different guide structures answer different questions

Corner-to-corner diagonals can help compare a composition’s overall direction against the frame. The underlying rectangular divisions provide smaller reference positions within that same canvas.

This does not mean every diagonal subject must align with a guide. Use the structure to inspect a design choice, then judge whether it helps the actual subject and intended composition.

Use Custom for exact cell planning

Special guide types are composition aids and do not all represent the row and column values as simple rectangular divisions. Custom is the appropriate mode when you need predictable counts or coordinate labels.

The designer changes the grid geometry and appearance as a whole. It does not let you drag individual guides, create unequal columns, or export editable vectors. Save the original source so you can compare another guide later.
