A custom-size page is useful when a jar or pouch needs a label that differs from a ready-made format. Start with a measured paper rectangle that fits the container. The Canva page then has a physical target, and you can judge the artwork at the size it will be printed.
01
Choose the finished size before opening the editor
Wrap plain paper around the package and mark the usable area between its shoulder, seams and base. Cut a rectangle within that area and hold it in the intended position. Measure its width and height. On a tapered jar, compare the top and bottom edges before deciding whether a rectangular shape sits flat.
For an illustrative preserve jar, your approved paper proof might be 60 mm wide and 45 mm tall. Record those dimensions and the jar model. If a print provider supplies the cut size, work from that specification and ask how it wants bleed supplied. A screenshot of a styled package does not establish its dimensions.
02
Enter dimensions in a consistent unit
Use Canva’s custom-size design controls to enter the width, height and unit. Read the width and height back before adding artwork. A 60 by 45 millimeter page is a different object from a 60 by 45 pixel page, even though the same two numbers appear in the fields.
If you are adapting an existing template, keep a source copy and check which resize tools are available on your account. Creating a fresh page and moving editable artwork into it can be a practical route when the existing-design resize feature is unavailable. Check every element after moving it.
03
Rebuild the information hierarchy at the new size
Place the brand, product name and variant first. Then work through the secondary information that belongs on that panel. A proportionally reduced label can leave fine text too small, so judge the words at final size instead of keeping every original proportion.
Suppose the original layout has a large botanical border and four lines of supporting text. On the smaller preserve label, reduce the border’s footprint and give the product name more usable width. Keep required information in a readable place on the complete package rather than squeezing it into a decorative corner.
| Checkpoint | What to compare |
|---|---|
| Page setup | Finished width, height and selected unit |
| Artwork | Readability and space around the longest wording |
| Paper proof | Measured print size and fit on the actual jar |
04
Measure the exported proof
Download in the file type requested by your printer. Print a plain-paper sample with scaling checked, then measure the result with a ruler. If the print is smaller than the intended cut size, investigate the print dialog’s scaling before changing your Canva artwork.
Tape the proof onto the filled package and photograph it from the front. Check the name, borders and any curved edges. Keep the approved measurement and export together so the next scent or flavor starts from the same physical specification. Repeat this check when you change the vessel.
BEFORE YOUR NEXT STEP
Your practical checklist
- Measure a paper label on the final package.
- Confirm width, height and unit.
- Review the information after transferring artwork.
- Measure an actual-size print.
Questions & answers
Can I copy a template into a smaller custom page?+
Yes, when its editable elements allow it. Review text size, wrapping and spacing after copying because proportional scaling can make small details difficult to read.
Does choosing millimeters guarantee the printed size?+
The page dimensions define the design. Export and printer scaling still need checking, so measure a physical proof before the production run.
