Note: For AprilTags 11-16 the stickers are 9 inches square. with a different cute line around them than the other tags. The graphic is still the correct size but care needs to be taken if using these tags to install them in the correct location relative to the other field components. If using the alignment notch at the top center of the back plate, the plate and sticker assembly will need to be mounted 3/4 in. lower than specified in the manual (measured from the bottom of the plate) for the tag to be in the right location.
