Our most versatile logo.
The block S with tree is one of the most recognized logos of Stanford University. The tree is based on the rendition of El Palo Alto, the tree seen on the Stanford seal. The symbol was updated in 2014.
For the Stanford block S with tree, the preferred presentation is in two colors: Cardinal red and Palo Alto green. The block S with tree in one color may be used when the preferred two-color version is not possible or appropriate.
University-approved colors shown below must be used for logos and matched for all digital projects, print and promotional items.

Make it large enough to read.
The block S with tree should always be reproduced at a size where it is clearly legible in the medium in which it appears. The minimum size is 3/8 inch for high-resolution printed materials. The block S with tree may need to be rendered larger than this minimum size when reproduced via low-resolution media to retain design integrity.
Give it room to breathe.
Whenever possible, allow at least 1/4 the height of the block S with tree at any given size and extend on all sides of the block S with tree. Do not place other graphics or typography in the minimum clear space area, except for trademark designations when appropriate.
The block S with tree symbols should not be altered in any way, such as by extending or condensing the emblem, outlining or adding borders, adding drop shadows or other special effects, or extracting the tree as a stand-alone symbol.
