This category can range wildly from advertising posters, vehicle wraps, 2 story billboards, etc. The variable to consider is the distance the viewer will be from the material. A person driving on a highway will never be able to discern the difference between 300dpi on a billboard and 40dpi. You would up close, of course, but the only people viewing a billboard up close are those installing it. Most advertising posters can get away with 100ppi. Vehicle wraps, much less.
The vendor may ask you to provide art at a smaller size than the actual printed size. For instance, if a billboard is to be 20' wide, the vendor may ask you to send a file 20 inches wide. If the billboard will be printed at 40ppi, then your 20" wide file would need to be set to 480ppi to allow for the scaling (12X40). Hope this helps.
