I Changed the Design 30%. Am I Safe?

There is no fixed modification percentage that clears a design. The US Copyright Office says there is no formula guaranteeing that a predetermined percentage or amount of a work may be used without permission. Counting edits is not a substitute for reading the license or assessing the relevant rights.

Reviewed September 30, 2026. This post distinguishes US copyright guidance from a vendor’s license conditions. Practical information, not legal advice.

License conditions and fair use are different questions

A license may require you to alter an asset before a particular use. The question is whether your use meets that agreement’s terms and whether the grantor has the authority to give those rights.

Fair use is a separate US copyright doctrine that can permit some unlicensed uses. The Copyright Office describes a case-specific assessment involving the purpose and character of the use, the nature of the copyrighted work, the amount and substantiality taken, and the effect on the work’s potential market or value.

The amount used is one factor, so quantity is not irrelevant. But no percentage is an automatic permission threshold, and changing 30% does not decide the other factors. The Office describes transformative uses as adding something new, with a further purpose or different character, rather than substituting for the original. A recolor, new caption or small borrowed fragment cannot be declared safe from that description alone.

A marketplace’s transformation standard is not a legal clearance rule

Design Bundles’ current guidelines say purchased elements must be edited, rearranged, overlapped and combined with other distinct graphics or text so the original asset is a component of a new composition. They expressly say “simple recoloring or minimal text additions to an as-is graphic” do not meet that standard.

That is the vendor’s stated licensing standard for the uses to which it applies, not a universal fair-use test. Read its tier and use permissions too. Unlimited includes as-is POD rights for finished physical goods under the current overview, while digital-design terms require an original, non-competing transformed layout. Hobbyist is personal-only; transforming a Hobbyist download is not a stated route to commercial permission.

Design Bundles source note (September 30, 2026): its overview says Unlimited includes as-is POD, but its linked full Premium License still describes a separately purchased POD add-on. These pages conflict. Confirm the terms attached to your specific download before relying on as-is POD permission. See the line-by-line guide for both statements.

The same page says lifetime coverage follows the terms assigned to your tier at download. For an older asset, keep the applicable historical terms rather than assuming today’s summary controls it.

A better check before you list

Identify the asset, applicable grant and exact planned product. Does the agreement require modification for that use? Which standard does it state? Does the grantor have authority over the included material? Are there separate brand or other rights to check?

Visual recognizability is not a universal pass/fail test either. A design that still looks familiar is not automatically infringing; one that looks different is not automatically permitted. If a disputed permission or fair-use argument matters to your business, get qualified advice rather than a percentage verdict.
