  2. 2Enter your image's width and height in pixels or mm.
  3. 3Read the key grid lines and placement points to position your subject.

Why Composition Rules Help

Rule of thirds divides the frame into a 3×3 grid

Composition guides place your subject where the eye naturally travels, creating balanced, engaging images instead of a centered, flat look.

The rule of thirds and the golden ratio are starting points; break them intentionally once you understand why they work.

Frequently asked questions

What is the rule of thirds?

Imagine a 3×3 grid; place key elements on the lines or their intersections to make a photo feel balanced and dynamic.

Is the golden ratio better?

It is a subtler spiral-based guide some find more natural; both are tools, not laws — use what serves the image.

Should I always follow the rules?

No. Learn them, then break them with intent. Centering can be powerful for symmetry and minimalism.
