Size Guide

This poster is pretty impressive, crunching all of time from the Big Bang to Today into a normal-sized, 18" wide x 24" tall poster. The poster is G-rated, so it's classroom- and kid-friendly.

This is a poster of our original post, Putting Time in Perspective. You can also find a poster of the prettier, more bare-bones version of our post, made by Visual.ly, and a long, skinny version of this poster, on the poster home page.

Sizing Guide
