Ad sizes and specs cheat sheet

An image with the right composition is easier to adapt than one cut to an arbitrary rectangle. Start with the destination placement, then check whether its suggested aspect ratio suits your product and the amount of copy you need on the image.

This reference separates suggested dimensions from technical minimums. TikTok’s entry describes a video placement and cannot be exported as a still image here. Google responsive search ads use text assets; the image entries here are for responsive display ads instead.

• Choose the platform and placement you are making creative for.
• Read the recommended ratio, pixel size and file limits.
• Create your artwork at the largest listed size so it scales down cleanly.
• Check the platform page for the current figure before final export, as specifications change.

A square 1:1 feed image and a vertical 9:16 story image need different compositions, not just different crops. If you only have one landscape photo, crop for each placement and check that the product and text still sit inside the visible area.

Illustrative example, not a benchmark, customer result or prediction.

A good set of ad sizes covers the placements you actually buy and keeps key content away from edges. Specifications are reference points, and platforms change them, so use the date shown and confirm in the source.

• Placement and format.
• Platform updates.
• File size and type limits.

• Using one size for every placement.
