PosterSize combines AI-powered poster generation with a practical guide to poster dimensions. Users begin with a short creative brief describing an event, brand, product, or message, then choose an art direction such as editorial, minimal, vintage, bold type, illustration, or cinematic before selecting a canvas and resolution. The platform turns an initial idea into a visual starting point quickly and supports different formats with clear credit-based pricing without subscriptions or registration requirements. Users pay for one-time credit packs, while failed poster jobs are automatically refunded. PosterSize also includes a catalogue of standard sizes for print, social media, and presentations, including A4, A3, A2, A1, US Letter, 18 x 24 inches, 24 x 36 inches, Instagram posts, Instagram Stories, LinkedIn posts, and presentation slides. It is suitable for event organizers, marketers, artists, small businesses, designers, and anyone who needs to create or plan an effective poster.
