HOW TO MAKE THE MEASUREMENT 1. Measure the distance from one post to the next post. 2. Based upon those measurements, subtract 10-15CM feet. For example, for a 210CM by 310CM measurement we suggest one 200CM by 300CM product. For any questions please call us In AMAZON for further assistance. NOTE: ---Our sun shade sails have curves on each side to enhance pull strength and prevent drooping on the sides. Due to the curved sides on sun shade sails, the product may have 1-6 inches deviations on side length. For our hand-made products, deviations of 2 inches more or less is not uncommon. Thus, any deviations between 0 and 8 inches are acceptable for our products. ---Due to curves, please keep in mind that our sun shade sails will be 4-6 inches shorter in middle width. ---If you have further requests like a straight side on all/one/two sides, exact sides length, or with buckles on the sun shade sail sides, or questions like installation and maintenance please contact us.
