How to measure your gable jaali, roof border or jaali panel
Five minutes with a measuring tape and you will know your exact price before you contact anyone. No site visit needed.
01Before you start
Three things to have ready.
- A measuring tape long enough for the span — a 5 m tape covers most homes
- Someone to hold the other end if you are measuring a gable or a long roof edge
- A photo of the area on your phone — useful when you send your measurements to us
Everything on this page is measured in feet, because that is how PVC work is priced in India. If your tape reads centimetres, divide by 30.5 to get feet.
02Gable jaali — the triangle at the top of your wall
The peaked section under a sloped roof, common on Kerala-style and coastal Karnataka homes.
- Base width (B) — measure straight across the bottom of the triangle, wall edge to wall edge.
- Height (H) — measure from the centre of that base line straight up to the apex. Vertical, not along the slope.
½ × 16 × 6 = 48 sq ft. At ₹180 per sq ft for 8 mm:48 × ₹180 = ₹8,640
We charge the triangle, not the rectangle. On that example, billing the full 16 × 6 would have cost ₹17,280 — nearly double, for material we never cut. Worth checking whether a quote you have received elsewhere has done that.
If your gable is not a clean triangle
Many gables have a small vertical section at the bottom, or a stepped edge. Measure it as a triangle plus a rectangle and add them together — or send us a photo with the overall width and height and we will work it out.
03Roof borders — measured by running foot
Decorative edging that runs along the eaves. Priced by length, not area.
Run your tape along the roof edge where the border will sit. If it goes around more than one side, measure each stretch and add them together. Round up to the nearest half foot.
22 + 14 + 14 = 50 running ft. At ₹120 per running foot for 8 mm:50 × ₹120 = ₹6,000
Add a little margin. We suggest ordering about 5% more than you measure, to allow for cutting at corners and joins. On 50 ft that is roughly 2–3 extra feet. It costs far less than discovering you are short once the fitter is on site.
04Jaali panels — plain rectangles
Partitions, balcony screens, pooja room panels, window screens, façade panels.
8 × 4 = 32 sq ft. At ₹110 per sq ft for 5 mm:32 × ₹110 = ₹3,520
For a partition that must fit an opening exactly, measure the opening in three places — top, middle and bottom — and give us the smallest reading. Openings are rarely perfectly square, and a panel cut to the widest point will not go in.
05Which thickness should you choose?
Thickness drives both rigidity and price, so it is worth getting right rather than defaulting to the cheapest.
| Thickness | Best suited to | Notes |
|---|---|---|
| 5 mm | Indoor partitions, pooja rooms, small decorative panels | Lightest and cheapest. Not for exterior or spans over about 4 ft unsupported. |
| 8 mm | Most gables and roof borders, balcony screens | The usual choice. Good balance of rigidity and cost. |
| 10 mm | Larger gables, exposed elevations | Noticeably stiffer over wide spans. |
| 12 mm | Wide façades, wind-exposed coastal sites | Holds its line where an 8 mm panel might flex. |
| 18 mm | Deep-relief work, large architectural features | Heaviest and most rigid. Creates real visual depth. |
06Minimum order and freight
- Roof borders: minimum 20 running feet
- Gable jaali and jaali panels: minimum 10 sq ft
Below the minimum we will still quote — we bill at the minimum and tell you we have done so. That is usually still cheaper than the freight on a single small panel.

Usually not. Almost every job we do is measured by the customer using this guide. For very large or unusual elevations we ask for photos and an architect’s drawing rather than send someone, which keeps the cost down.
We confirm the final area with you in writing before production, and you approve a design preview showing the exact dimensions. Nothing is cut until you have signed off on both.
In most cases yes. Send a photo and we will tell you honestly whether it can be CNC-cut in PVC, and at what thickness it will hold together. Very fine patterns sometimes need adjusting so the thin sections do not become fragile.
PVC foam board is waterproof and will not rot, warp or be eaten by termites, which is why it has largely replaced timber for gables and roof borders in coastal homes. It is supplied in white as standard and can be painted.
Triangle. We charge ½ × base × height, which is the area actually cut, at the per-square-foot rate shown for your chosen thickness.
