I can't tell the difference between standard yield and high yield.

Normally, a high-yield cartridge will be a much better value as they usually produce twice the number of prints for just a few dollars more than standard yield cartridges. However, this does not necessarily mean that there will be a difference in the size of the cartridge.

Additionally, remanufactured or compatible ink cartridges that are considered standard yield will sometimes contain more ink than the printer brand cartridge.
