General Rules

  • The shamrock should not be altered in any way.
  • Always use the official electronic artwork provided by Fighting Irish Media and Notre Dame licensing.
  • The standard orientation of the shamrock should remain the same. It should always keep the tilt that is displayed to the right and should not be flipped backward.
  • The registration mark should be included for all merchandise and apparel but may be omitted for general use.
  • Do not use the shamrock as the main mark for center court/field experiences. Use the Notre Dame monogram as the main mark and use the shamrock as a smaller, supporting, and decorative element.

Minimum Size

The shamrock is a simplified visual asset that can be reproduced at a smaller size than the leprechaun. Adhere to the following size guidelines.

Shamrock Minimum Print Size

Print Applications

The shamrock should not be scaled smaller than 0.5 inches in height. Use good judgment when designing and executing across different mediums and substrates. If legibility becomes an issue, increase the size to ensure the integrity of the visual asset.

Shamrock Minimum Digital Size

Digital Applications

The shamrock should not be scaled smaller than 35 pixels in height. Use good judgment and scale appropriately to make sure the integrity of the visual asset stays intact.

Shamrock Clear Space

Clear Space

The clear space is the protected area around the visual asset that must be maintained to ensure no other graphic elements interfere with its clarity and integrity. It is also the minimum space the visual asset may be placed from any corner of an artboard in which it is placed. Respect the developed boundaries and maintain appropriate separation.

The defined clear space is “X” units. The “X” unit correlates directly 1/6th the height of the shamrock.
