Understanding Tarp Sizes

NOTE: Please note that tarp sizes listed on our site refer to the "cut size," which is the dimension of the material before hemming. Finished tarps are typically 2-4 inches shorter on each side due to the folded and reinforced edges. The original material width (e.g., 61" for vinyl, 144" for poly) can also affect the final dimensions. If you require a tarp with exact finished measurements, please contact our Customer Service team at sales@tarpsamerica.com for assistance.
