Sizes, ratios, file limits and lengths for every major ad placement. Each one links the platform page it was read from, and where a platform does not state a value, the guide says so.
Everything runs in this browser. Files you add are never uploaded, stored or sent to analytics.
Every row was read from Meta, TikTok, Google, LinkedIn, X or Pinterest documentation and links the exact page. No spec is copied from another round-up.
YouTube does not state a recommended size for Shorts ads and X does not state an image file limit. The guide says "Not stated" instead of filling the cell with a guess.
Pick a platform and image or video and copy just those specs, with their sources, into a brief or a ticket.
Reels and Stories rows carry Meta's keep-clear margins, and the safe zone checker shows them over your own creative.
Choose where the ad will run and whether it is an image or a video.
Build at the listed size and ratio. A file that is close but not exact is where platforms crop and compress in ways you did not choose.
Specs change. Each card links the platform page, so a two-minute check before an expensive campaign is easy.
Platforms accept a range of files, but they display a specific frame. A file at the wrong ratio gets cropped to fit, and the crop is decided by the platform rather than by you, which is how a product ends up cut in half or a headline loses its first word. Resolution matters too. A file below the recommended size is upscaled and looks soft; one far above it is compressed hard on upload. Building at the listed size gives the platform the least to change.
Each number was read from the platform's own ads documentation on the date shown under the guide, and each card links the page. When a platform leaves a value unstated, the card says so rather than borrowing a figure from elsewhere. If you spot a spec that has changed, the linked page is the authority, not this guide.
Advibly turns your brand into finished ads: product-in-hand UGC videos, static image ads, carousels, and explainers. Same thinking as this free tool, pointed at the thing that actually takes time.
