Here is the thread as buyers actually ran it.* Also asked as: It has 5 windows in it instead of 3.; 5 windows, all at slightly different angles. > **The quick answer:** Yes: a bay window seat cushion can have any number of angles, including 5-window, pentagon and hexagon bays. Send a rough sketch with every side or segment measured, the angles if you know them, and the depth at each breaking point. The workshop turns it into a template for you to check, then you order by the nearest length and width range. ![Olive gold velvet trapezoid window seat cushion with brown piping in a dining bay beside a teak table and chairs](https://cushionguide.com/media/bay-window-cushions/olive-gold-velvet-trapezoid-dining-bay-seat-1600.webp "A bay seat that doubles as dining seating, in olive gold velvet with a brown welt to match the teak furniture.") ## Key facts - Bay window cushions with any number of angles are made regularly, including pentagon and hexagon shapes. - Measure every side or segment, plus the angles if you know them. - Give the depth at each breaking point, not only the deepest one. - Your sketch comes back as a template for you to check before anything is cut. - Order by the length and width ranges that cover the seat, then write the full shape in personalization. - A real 5-window bay ran 115 7/8 in (294 cm) long and 16 in (41 cm) deep at its deepest, made 4 in (10 cm) thick. ## “It has 5 windows, not 3. Can you still make it?” Yes. Multi-angle bays are made regularly: 5-window bays, pentagon and hexagon seats, windows each at a slightly different angle. The count of angles doesn't matter. The count of measurements does. Angles are just lengths in disguise. Give every side and every depth and the angles fall out of the drawing. The [bay window calculator](https://cushionguide.com/studio/bay-window-calculator/) is a good place to test your sketch first. ## “What exactly do I measure?” 1. **Sketch the seat from above**: Rough is fine. Number the segments along the back wall, left to right. 2. **Measure every side**: Front edge, each back segment and both end sides. 3. **Add a depth at each breaking point**: Wherever the wall changes direction, measure straight out to the front edge. 4. **Check the template**: Your sketch comes back as a template to check before cutting. ## “So is it a trapezoid with extra edges?” For ordering, yes. Choose the length and width ranges that cover the seat, for example 78 in (198 cm) and 22 in (56 cm); they only set the size bracket. Then write the full shape in the personalization box: front, back, angled sides, end sides and depth. The [5-sided bay window cushion pattern](https://cushionguide.com/guides/5-sided-bay-window-cushion-calculator/) walks through the layout, and the [bay window cushions](https://cushionguide.com/cushions/bay-window-cushions/) hub shows finished seats. ## A 5-window bay, 115 7/8 in end to end A buyer sent a bay of five windows, each at its own angle, with every segment measured and a depth at each breaking point. At its deepest the seat was 16 in (41 cm); end to end, 115 7/8 in (294 cm). It was cut at the standard 4 in (10 cm) thickness, in linen with contrasting piping. Nothing exotic. Just a longer list of honest measurements. > **Tailor's margin:** A 5-window bay seat has six corners along its back wall: write a cushion depth at every one, not only at the deepest point. ## Buyer questions **A common question:** Can you make a bay window cushion with several angles? **The workshop's answer:** Yes, multi-angle bay window cushions are made regularly. Send a rough diagram with the measurements, and the workshop checks and confirms it. **A common question:** My bay is an odd shape: 5 windows at different angles. Is that possible? **The workshop's answer:** Yes, many angled bay cushions have been made. Send a rough sketch with every side's length and the angles for a quote and advice. **A common question:** Mine has two extra edges, more pentagon or hexagon than trapezoid. Can you make that? **The workshop's answer:** Yes. Send the exact length of every side or a simple sketch, and it comes back as a template for you to check. Then pick the ranges that fit and write the full shape in personalization. ## Questions buyers ask next ### What is a breaking point on a bay window seat? Each corner where the back wall changes direction, usually between two windows. The seat depth can change there, so a depth is needed at every one. ### Are lengths enough, or do I need the angles too? Lengths are enough. Every side plus the depth at each breaking point lets the shape be drawn and checked; angles are a useful extra. ### How thick should a 5-window bay cushion be? The 5-window example was made at the standard 4 in (10 cm). Thickness is chosen apart from the shape; the [window seat thickness pattern](https://cushionguide.com/guides/window-seat-cushion-thickness/) helps you pick. ## Related at the atelier - [Can you make a custom-shaped floor cushion for my corner or reading nook?](https://cushionguide.com/answers/custom-shaped-floor-cushion-corner-reading-nook/): A floor cushion can be made to the shape of your corner, bay or reading nook when you send the shape and measurements before ordering. - [What measurements do you need for a trapezoid bay window cushion?](https://cushionguide.com/answers/trapezoid-cushion-measurements-needed/): Send every edge of the trapezoid: the front, the back, both angled sides and any clipped corners, plus one straight depth and the thickness. - [How do I label the sides on my trapezoid cushion drawing?](https://cushionguide.com/answers/trapezoid-cushion-drawing-label-sides/): Give every edge of the trapezoid a letter and a length: A, B, C and D for the four sides, plus E and F for clipped corners or end pieces, then add the depth and thickness. - [5-sided bay window cushions: working out angles, sections and seams](https://cushionguide.com/guides/5-sided-bay-window-cushion-calculator/): Measure a 5-sided bay window cushion edge by edge: every back segment, the short end returns, the front and the depth at each break, each with its own letter. - [Bay Window Cushion in Dusty Rose Linen, Cut to the Angle](https://cushionguide.com/readings/dusty-rose-bay-seat-cushion-dressing-room/): A bay window cushion starts with a drawing, not a fabric: mark every side length and both angled ends, and the quote comes back exact. - [Bay Window Cushion Piping, Read on a Five-Sided Bouclé Seat](https://cushionguide.com/readings/rust-boucle-five-sided-bay-window-cushion/): On a five-sided bay window cushion, self piping is the safe choice: it defines every facet by shape while keeping one color around all the angles. - [Measuring a 3-sided bay window seat cushion, panel by panel](https://cushionguide.com/guides/bay-window-seat-cushion-3-sided/) *± 1/4 in — Nate* --- Written by Nate Kowalski (https://cushionguide.com/masters/nate/) for CushionGuide (https://cushionguide.com/about/).
