PosterSize combines AI-powered poster generation with a practical guide to poster dimensions. Users begin with a short creative brief describing the event, brand, product, or message they want to communicate. They can choose an art direction such as editorial, minimal, vintage, bold type, illustration, or cinematic, then select a canvas and resolution.
The platform turns an initial idea into a visual starting point quickly. It supports different formats and offers 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, plus practical guidance on viewing distance, purpose, ratio, bleed, trim, safe areas, paper stock, colour profiles, readable typography, and testing layouts at phone size. It is suitable for event organizers, marketers, artists, small businesses, designers, and anyone who needs to create or plan an effective poster.
