Questions & Answers

As answered by people managing AdSize and Comapi.

What makes your product unique?

AdSize's answer

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.

Why should a person choose your product over its competitors?

AdSize's answer

  • Accuracy you can trust — sourced from official platform docs with a confidence indicator, not copied from stale blog posts.
  • Live previews — every size rendered to scale with safe zones, so nothing gets cropped on export.
  • More than sizes — compare two platforms side by side, decode jargon in the glossary, and check any market with geo profiles before you spend.
  • Truly free & private — no registration, no ads, no tracking, no personal data collected.
  • Multilingual & fast — 6 languages, instant search, clean mobile UI, kept up to date for the current year.

How would you describe the primary audience of your product?

AdSize's answer

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.

What's the story behind your product?

AdSize's answer

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sizes are scattered across dozens of platform help pages that change without notice, and most "cheat sheets" online are outdated within months.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.
