Sizing Guide

Choose the right size for your space

Use this guide to compare the poster sizes available across Redline products. Product pages show the exact formats offered for that artwork; the guide below helps you picture how each size will work in your home, office, garage, or studio.

Poster dimensions

A2	42 × 59.4 cm	16.5 × 23.4 in	A strong focal point above a desk, sideboard, or workstation.
A1	59.4 × 84.1 cm	23.4 × 33.1 in	Large feature walls, garages, offices, and statement interiors.

Framed and unframed options

All framed options use premium wood frames and are supplied ready to hang. The premium wood frame adds a refined border and extra presence on the wall, while the museum-quality matte poster option is ideal if you prefer your own frame or a lighter, more minimal display.

Available options can vary by product. Select your preferred Product and Size on the individual product page before adding it to your cart.

Measuring your space

For the best fit, mark the outer dimensions on the wall with painter’s tape before ordering. Leave comfortable breathing room around the artwork, especially when creating a gallery wall. Artwork may be portrait or landscape depending on the design; check the product imagery for its orientation.
