Compare Paper Sizes on Handy Website

by kevin on July 6, 2018

What? Another new website? My latest addition to the family is, a site that instantly displays paper sizes and visually compares sizes with one another. Just choose a paper size from the drop-down menu to see the size overlaid on a letter-size sheet. is a convenient resource for graphic designers, crafters, or anyone who does business internationally. It’s also a nice complement to, my printable paper site, and, my printable planners site.

The site also displays the standard and dimensions of the width and height in both millimeters and inches. The standards include: American National Standards Institute (ANSI), Architects Standard (Arch), International Organization for Standardization (ISO), United Kingdom (UK), and United States (US).

For example, if you select A5 paper, you’ll see that it’s ISO standard and its dimensions are 148mm by 210 mm or 5.8 inches by 8.3 inches. Then, they can click to compare A5 paper to any of the dozens of paper sizes covered at

Beyond the printables, other helpful sites I’ve developed in the last year include for seeing the pH of various acids, bases and common substances. Plus, there are several math resources: for fractions, for percentages and for simplifying fractions.
