How this particular wall divides
The 2 columns leave 1 interior gaps. The two side margins use 12 inches and the gaps use 4 inches, leaving 104 inches for the frame outlines. Dividing that space by 2 gives an outer box width of 52 in (≈ 52″).
Height = (84 − 2 × 8 − 1 × 5) / 2 = 31.5 in
The two rows are separated by 5 inches of clear wall. Each row starts from its own top mark in the table; keep the gap outside both trim outlines. The top and bottom margins are each 8 inches. The frames are wider than they are tall, with an outer height-to-width ratio of 0.606. Use these proportions as a tape mock-up, rather than assuming they suit the furniture on your wall.
Centerline and boundary checks
The center of the wall falls in the clear gap between the two middle columns. The first outer left edge is 6 in (≈ 6″). The last column starts at 62 in (≈ 62″) and ends at 114 in (≈ 114″), leaving the intended 6-inch right margin. The final row ends at 76 in (≈ 76″). Check these far edges from the same origin you used for the first box.
The 1.25-inch face width reduces each inner dimension by 2.5 inches. That leaves 49.5 in (≈ 49 1/2″) by 29 in (≈ 29″) of exposed wall within each outline. The listed cut lengths still use the outside long points. If you want a particular inner opening instead, account for both sides of the profile when you revise the outer geometry.
What the material count means here
This layout needs 8 horizontal pieces at 52 in (≈ 52″) and 8 vertical pieces at 31.5 in (≈ 31 1/2″). There are 16 individual pieces, each with two 45-degree ends. Their combined finished long-point length is 668 inches, or 55.667 feet. The 10% linear allowance adds 66.8 inches to that budget and produces a 8-stick length estimate.
The longest piece is 52 in (≈ 52″). With a 0.125 in (≈ 1/8″) blade and 0.354 in (≈ 3/8″) reserved for the two 45-degree cuts on each piece, the longest-first cutting plan uses 8 working sticks, leaving 94.343 inches of combined tails after kerf. Those tails may be several separate pieces and cannot be treated as one long board. The combined purchase figure is 8 8ft sticks. Turning off the 10% allowance changes the linear figure to 7 sticks and the combined purchase figure to 8; the working plan still controls the purchase because whole pieces must fit.
Two alternatives worth taping on the wall
Adding one column gives 3 across and 6 frames in total. With the same margins and gaps, each becomes 33.333 in (≈ 33 5/16″) wide by 31.5 in (≈ 31 1/2″) high. The finished material total changes to 64.833 feet, and its combined 8ft purchase estimate is 10 sticks. More columns make narrower panels while adding vertical sides; they do not simply divide the current cut list into smaller pieces.
Keeping the current counts and making each side margin one inch larger changes the outer width to 51 in (≈ 51″), a reduction of 1 in (≈ 1″) per frame. Its left outer edge shifts to 7 inches. The height stays at 31.5 in (≈ 31 1/2″) and the total becomes 55 feet. This option gives the wall edges more breathing room without moving the top and bottom boundaries.
Before using this cut list
These are calculated examples, not measured installations. Confirm the full 120 × 84 inch area, the actual trim face width, and the locations of cover plates or casing. Mark one frame, dry-fit its corners, and confirm its outer size before cutting the rest. Fractions are rounded display values; use the independent marks in the table so small rounding differences do not collect at the far margin. The stock plan assumes clean 96-inch sticks and the entered kerf. Allow separately for defective ends or additional practice pieces.
