How do I resize a Canva campaign without changing the approved master?

Protect the approved master

First identify the exact approved Canva design and record its current name, page count, visible dimensions, and approval state. Treat this design as read-only during the test. Do not begin with the direct Resize control on that item, because direct resize changes the current design.

Open a non-destructive working copy if your account interface provides that option, then use Copy and resize on the design you intend to adapt. The resulting item should be treated as a derivative with its own name, rather than as a replacement for the approved master. Canva’s available controls and document support can differ by account, so use the labels actually shown in your interface.

1. 1. Record the master design name, dimensions, page count, and the page or pages approved for reuse.
2. 2. Open the design and choose Copy and resize, not direct Resize.
3. 3. Enter the required destination size only after confirming that the destination is being created as a separate item.
4. 4. Give the derivative a distinct working name, such as Campaign Spring Social Derivative, where that wording is illustrative.
5. 5. Open the derivative and inspect the selected pages before editing content.

Control page scope

Page selection defines the scope of the resize. If only one campaign page is approved for adaptation, select that page rather than allowing the operation to include every page. Record which pages were selected so another reviewer can compare the result with the master.

If you use Resize to Selection, remember that Canva bases the result on the selected bounds. This can produce a different outcome from resizing the full page, especially when only an element or a group is selected. Use it only when the intended asset is the selected bounds, not the complete campaign page.

Illustrative exercise

Illustrative exercise: define Asset A as the approved master named Campaign Spring Master, with two pages and an illustrative page size of 1200 by 628 pixels. Define Asset B as the derivative named Campaign Spring Square Derivative, created with Copy and resize for an illustrative 1080 by 1080 pixel destination. These are separate assets before any A/B comparison.

Compare A and B only after Asset B exists. Pass means Asset A still has its recorded name, page count, dimensions, and approved visual content, while Asset B has the requested destination size and contains the intended selected page. Fail means A has been resized, renamed in a way that obscures its approved status, lost pages, or changed visually because the resize was performed directly on the master.

Verify before handoff

Inspect evidence in both items: the Canva item names, dimensions shown in the editor, page count, selected-page scope, and the visual placement of key campaign elements. Compare the derivative against the master for unintended changes such as missing text, clipped artwork, or a page included by mistake.

Presentation pages resized to video can become separate video pages. If that behavior appears in the account interface, verify that the resulting page structure is acceptable before delivery rather than assuming it remains a normal presentation page.

The acceptance condition is specific: the approved master opens with its recorded dimensions, page count, and content intact; the derivative is a separate item with the requested dimensions; and the derivative contains only the intended page scope with no unreviewed clipping or missing campaign content.
