Custom Posters: Turning a Text Prompt into Wall Art

AI wall art has a tell: square images awkwardly cropped into poster frames. The fix is simple: generate at the right aspect ratio from the start, and pick styles that embrace print.

Match the ratio to the paper

Quality poster prints come in √2 paper formats (like 16.5″ × 23.4″) in vertical or horizontal orientation. Generating your artwork in a matching portrait or landscape ratio means no cropping surprises: the composition you approved is the composition on your wall.

Styles that print beautifully at poster scale

• Minimalist line art: huge negative space reads as intentional design
• Vintage travel-poster style for cities and landscapes you love
• Watercolour botanicals: soft edges hide any AI artifacts
• High-contrast woodcut scenes: dramatic from across the room
• Cyberpunk cityscapes for offices and gaming rooms

A note on resolution

Posters are unforgiving: at 23″ wide, every pixel matters. Look for services that print at 300 DPI and upscale generated art before printing, or your beautiful design becomes a blurry rectangle.
