AdSize is a free, no-signup reference for advertising and social media creative sizes that stays genuinely current — and goes well beyond a plain size chart. Every dimension, max file weight, accepted format and video spec is cross-checked against each platform's official documentation and carries a data-confidence indicator. Each size has its own page with a live, aspect-accurate preview (feed post, 9:16 phone with safe zones, cover, banner), so you catch cropping before you export. It covers 30 ad and social platforms across 310 sizes, in 6 languages, and adds tools most charts don't: side-by-side platform comparison, an ad-terminology glossary, and geo profiles for 241 countries. No ads, no tracking, no account.
Designers and marketers who produce ad and social creatives — in-house teams, agencies and freelancers — plus media buyers, affiliate/performance marketers and social media managers. Essentially anyone who needs the exact, current spec for a platform before exporting a creative, and — via the geo guide — anyone planning campaigns across different markets.
AdSize grew out of a recurring frustration: creative sizes are scattered across dozens of platform help pages that change without notice, and most "cheat sheets" online are outdated within months. The goal was one always-current, free reference — every size verified against the official source, with live previews so you see exactly what you're building. It expanded from a size table into a full toolkit (comparison, glossary, per-country geo profiles) and multiple languages, built to stay fast, privacy-friendly and free.
