All waterslide decals are between 3 and 3 1/2 inches in height.
If they are more rectangular in shape, then they may be shorter but no longer than 4 inches wide.
They are sized to fit the top of a 30 oz cup with the steep taper.
If you need a different size, you can use the custom waterslide listing and contact me regarding the specifics.
These are inkjet printed with permanent ink and do not need to be spray sealed.
