How do I know what size of Panel to order? We make five standard sizes of panels for you to select from.  The panel size you choose is based on; appearance and wall application.   For customers who are using the panels as a headboard you first have to know the width of your mattress and how high you want your Headboard to go. Here are the standard mattress widths; Twin/Single                39" or 99 cm Double                       54" or 137 cm Queen                        60" or 152 cm King                            76" or 193 cm California King          72" or 110 cm Now determine the look you want.  If you are unsure, please have a look at our Gallery of Pictures.  Also another determining factor is Budget.  We have fabrics and panels that will work within most budgets. Our panels come in five sizes and the rectangle panels can be hung both horizontal and vertical.  This makes them versatile when determining your panel orientation. For example, on a Queen bed with a width of 60", you can use the following panels; Three wide Amanda panel 20"x20" Two wide Lorna panel 30"x20" (hung horizontal) Three wide Lorna panel 20"x30" (hung vertical) Three wide Gwendolyn panel 20"x40" (hung vertical) Two wide Eddy panel 30"x30" Two wide Robert panel 30"x40" (hung vertical) As you can see, it is up to you how you want to hang your panels and the look you want to achieve.
