Printable ruler and printable size guides to help everybody find the right label size for their project or container

"How do I find the right label size" is a question we get asked pretty regularly. Whether it's difficulty measuring rounded bottles or too many label sizes to choose from, we know it's a challenging hurdle to buying labels.

To help solve this widespread problem, we developed the following free printable label tools. They're sure to help you get the right measurements for labels that fit.

Simply click on the files below to open them in a new window. Click the download button and open them in Adobe Acrobat Reader. Then, print them on standard printer paper and grab your scissors!

Be sure to check your printer settings to ensure your documents print correctly. In the printer dialog box that opens after clicking print, look under "Page Scaling," and select "Actual Size" or "None." Next, confirm that "Auto-Rotate and Center" is unchecked.

Printable Ruler

Our printable ruler is 10 inches in length to fit on a standard 8.5" x 11" piece of paper. Because it's flexible, it can bend and wrap to match any shape container.

How To Use The Printable Ruler

  1. Cut out your ruler using scissors.
  2. Confirm your ruler increments are accurate. (Credit cards have standard dimensions so you can use one from your wallet to check. It should measure 3.37 inches wide or 8.6 centimeters.)
  3. Measure your item. Line up the red line with your starting point and use your thumb or finger to hold the end in place before wrapping the ruler around the rest of your container. For items with angles, you may need to tape the ruler to your container to hold it in place while you wrap the rest. If you want a full-wrap label for your product, we recommend adding an extra 1/4 inch to your width dimension.
  4. Choose a label size. Visit Shop by Size, click "Filter by exact size" in the left sidebar, and enter your dimensions. If you're looking for a range, use the sliders to narrow your results.

That's it! Select the label configuration that's best for your product, and you're well on your way.

Can't find the label size you were looking for? We offer custom size labels. See if other customers have created your size for their needs or create your own.

Some containers are tapered, with a different top circumference than the bottom. If this sounds like your packaging, learn more about labeling tapered containers.

Frequently Questions and Answers

1. What’s the best way to double-check that my printed ruler matches the correct dimensions?

Ensure that when you print the ruler file, your printer scaling settings are set to Actual Size or None. Also, check that Auto-Rotate and Center are unchecked. After printing, you can verify the accuracy by measuring a known-size object.

2. Can I use the printable ruler on curved or irregular containers?

Yes, our free printable ruler is flexible because it’s on paper and can be cut out and wrapped around your container. When wrapping, line up the red start line, hold or tape the end in place, and wrap it around the container.

3. What if I can’t find a pre-made label size that matches my measurements?

If, after measuring, you don’t see a product size that matches your container, you can browse our custom label sizes.

4. What units are being used on the printable ruler?

The printable ruler provides measurements in inches, centimeters, and millimeters. When using the ruler, check the unit of measurement and match it to the product filters on the website.

5. I printed the ruler, but it appears to be slightly off when I measure a known object. What should I do?

Because you are printing, and paper may stretch or shrink, a slight variation is normal. Ensure that your printer's scaling is set correctly. If the variation is significant, you may want to calibrate by printing again or using a physical ruler or another measuring tool to double-check the accuracy.
