Principles of Design
Noun Project visual standards
Your icons should be well-crafted. Our curation team looks over your icons as if they were under a microscope, so remember to take the time to thoroughly look over them to make sure they follow our principles of design.
Your icons should not contain letters, numbers, or words unless universal.
Stick to one design style. Whether that is line, fill, or hand-drawn is up to you.
Your icons' shapes and lines should be connected and merged.
Shapes in your icons' designs should be aligned correctly within it.
Shapes used in your icons' designs should be spaced evenly.
Your icons should be clean and have no excess vector points, unless done in a hand drawn style.
Contain with a Purpose
Only use shapes to contain your icons if it helps communicate the noun, idea, or concept.
Your specified grouping of icons
Collections are a set of icons you've designed to upload that work together by sharing the same design style, with the best collections sharing style and theme.
Pro tip for creating a collection:
Often users are in search of a set of icons that have a cohesive feel for the project they're working on. By creating a collection, they'll likely download more of your icons, meaning more royalties for you!
Add to Existing Collection
If you have icons that you want to add to an existing collection, be sure to select the option on the right while on the upload page.
You will then see an option to the right to 'Create a collection' at the top of the page. If you press 'Add to a previously created collection' you'll see a list of all the collections you've started that you can add your icons to.
After you select the collection you'd like to add to, you'll have the option to upload icons to that specific collection.
