How to Create Event Posters at imgresizr.com

Start with a high-quality event photo or graphic. Upload to imgresizr.com and use the Resize tool to set your target poster dimensions. For a print-ready A4 poster, set 2480×3508px. Use the Enhance tool to make your background image vivid and impactful. Use the Caption or Text tool to add the essential event information: event name, date and time, venue and address, ticket price or registration link, and organiser contact details. Use large, high-contrast text that is readable at thumbnail size. Create both print and social media versions from the same source image by resizing to different dimensions. Compress the social media version for posting; keep the print version at full quality.

Event Poster Design Tips

  • The event name should be the largest, most prominent text element
  • Date, time, and location should be immediately visible without reading all the copy
  • High contrast between background and text is essential for readability
  • Include a QR code linking to ticket purchase or event page for print posters
  • Create both portrait (A4) and square versions for different social media placements
