Marble Window Sills Dimensions

Every window has a different width and depth where the window sill would be placed. However, there are standard width and lengths of windows typically used in the market. The 3 standard lengths of marble window sills available are 74″, 56″ and 36″.

The thickness of the window sills are usually 5/8″ (16mm). However, if requested as special orders, we can produce 3/4″ thick (20mm) window sills. Please do not forget that every special order requires a minimum order quantity and 10 weeks lead-time.

The depth (width) is the dimension that varies the most in our window sills. Since the opening of the windows varies a lot, we need to keep stock of 3″ to 12″ wide window sills in increments of 1″ (3”,4”x 4 ½”,5”,6”,7”,8”,9”,10”,11”,12”). These are standard sizes and we do not offer custom cuts locally. Please check our inventory to see the availability of all dimensions.

If your project meets our minimum purchase requirements, we will manufacture your order overseas and import them within an estimated delivery time frame of 8-10 weeks.
