The size of material you will want to order depends on the viewable dimensions, or screen size, that you would ultimately like to achieve. The article, How to Select Your Ideal Projector Screen Size, walks through the decision making process.
Once you have decided on a viewable width, simply multiply that dimension by your desired aspect ratio to determine the viewable height.
Carl’s Tip: When ordering raw material you’ll want to consider your installation method when deciding how much material to order.
For example, if you’d like to achieve a 105” viewable width, it would be a good idea to select material that is 110″ wide to allow 5″ of fabric to stretch over our wooden frame. If you’re going for a 16:9 aspect ratio, you would determine the height with the following calculation:
105″ x 9/16 = 59.0625 or 59 1/16″ | We have our viewable dimensions of 105″ x 59 1/16″
An aspect ratio of 4:3 would be 105″ x ¾ = 78.75 or 78 ¾”
If you plan to add a border to your screen, like black felt tape or back band trim, keep in mind that anything that overlaps the screen material will shrink the final viewable area.
2. Calculate dimensions of the wood frame
Take the desired viewable dimensions and add the width of any black felt tape or trim you might be using.
For example, if you’re using black felt tape that is 2” wide and trim that has an overhang of 3/16”, take the viewable width of 105″ and add 2″ twice and 3/16″ twice, to get a total frame width of 109 3/8″. Then take the viewable height of 59 1/16 plus 2″ twice and 3/16″ twice to get 63 7/16″. The frame dimensions are 109 3/8″ x 63 7/16″
If you’re going for a zero-edge look and are not planning to finish with tape or trim, your frame dimensions will match your viewable dimensions.
Cut two pieces of pine that are exactly as long as the frame. We recommend using 1×4’s.
Finally, cut three boards that are 7″ (twice the width of the 1×4’s: 3 ½”) shorter than the exact frame height – one piece will go in the center for stability.
Assemble the frame using your joinery method of choice. We prefer to use pocket screws and a simple pocket hole jig
Carl’s Tip: Adding flat L-shaped brackets in each corner is an option for added strength and stability.
Stretch & Staple the Screen Material
Thoroughly sand the corners and edges of your frame before stretching the screen to avoid snagging or tearing the material.
Lay the screen material on the floor with the frame on top.
Using heavy duty staples, start on the top and place several staples in the center (1). Move to the bottom and place several staples in the center (2), stretching the fabric straight across.
Then, move to the right side of the frame and place several staples in the center (3), stretching the fabric out from the center. Move to the left and place several staples in the center (4), stretching the fabric straight across.
Take your time; make sure the staples are close together and work out all ripples before stapling to the frame (or onto drywall).
At the top add a couple staples, about 2-3 inches to each side of the original staples (5 & 6). Make sure to stretch with even tension out from the middle. Repeat at the bottom (7 & 8), right (9 & 10) and left (11 & 12) sides.
Add 3 staples, again 2-3 inches apart, at the top of the frame (13-15 & 16-18). Repeat at the bottom (19-21 & 22-24), right and left sides. Again make sure to stretch with even tension out from the middle as shown in the diagram.
Continue adding 2-4 staples, evenly spaced and rotating to opposite sides until the screen is completely secured all the way around the frame. Do not staple in a circle around the frame, always rotate to the opposite side with even tension.
Carl’s Tip: Do not wrap our thicker, stiffer, non-tensioned materials. Folding or crimping a thick material will cause permanent damage. If you want to wrap the material over your frame, be sure to select a tension-mounted material such as FlexiWhite, FlexiGray and Ambient Light Rejecting (ALR).
Our Pro non-tension materials work best for roll-down applications or stapling directly onto drywall without building a frame. A fixed frame is possible but is extremely challenging to install due to the risk of waves and ripples.
Apply Optional Frame Finishing
If using, cut the Back Band Trim with a Miter Saw or Miter Box/Saw to fit your frame. Back Band Trim is a piece of wood molding that surrounds the exterior edge of the screen to create a professional looking frame.
Spray paint the back band trim black & allow to dry
Nail the back band trim to the frame
Add the black felt tape, on top of the screen material, cutting with a scissors or utility knife – do NOT stretch the tape
