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 a 20 oz cup and 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.
Inkjet printed images are more vibrant but need to be spray sealed by you. They do not come pre sealed. If dunked in water without sealing, the ink will dissolve.
Laser printed images are more muted/faded looking but do not need to be spray sealed. They are ready for the water.
