Our experienced Customer Service Team will assist in calculating the quantities required for your project based on the measurements you provide. However, please note that these calculations are estimates only, and we do not guarantee their accuracy. It is recommended to review and confirm quantities independently to avoid discrepancies or misunderstandings about the amount of product needed. If there are any disputes regarding product credits, these calculations will be taken into consideration, but the final decision will be based on the actual product usage and needs.
