How to Measure a Panoramic Roof
Edited by LesomTech
A model name does not define a panoramic roof. Glass shape, trim, opening mechanism and attachment points can change by model year, trim, market and whether the roof opens. Start by identifying the exact vehicle and roof variant before discussing a custom shade.
LesomTech develops custom sunshades in its own Dongguan factory. Production starts at 100 pieces per style; sample quantities and charges are agreed separately. The pack below supports a feasibility review and sample plan. It does not replace a physical fit check on the target vehicle.
1. Identify the vehicle and roof variant
Record the make, model, model year, body style, sales market and trim. Photograph the roof from the front, rear and both sides, with the roof closed and, where applicable, open. Note whether the glass is fixed or movable and whether the vehicle has a sunroof, panoramic roof, roof rails, antenna or sensors near the glass.
Keep regional or production-period differences as separate entries. If the roof, headliner or trim has been repaired or modified, say so before measuring. A photo of the exterior alone does not show the trim gap, headroom or attachment surfaces the shade will use.
2. Fix datum points before measuring
Choose references that will not move: the front and rear glass edges, the vehicle centerline, a trim seam or a fixed body point. Mark them with low-tack tape and photograph each mark with a ruler in frame. Measure in millimetres and state the method used.
Record the glass width at the front, middle and rear, the length along the centerline, the glass-to-trim gap and headroom at the driver and passenger positions. Note curvature or a raised frame. A single maximum width is not enough to define a panel that must follow the opening.
3. Photograph attachment and storage clearance
Photograph the proposed clip or frame contact areas, trim edges, sun visors, sensor covers and any drainage or wiring that must remain clear. Show the shade's intended storage position and measure the space available for a folded panel or roller cassette.
Describe how often the shade will be removed, whether it must operate with the roof open, and any cleaning or removal instructions. These answers affect the frame, clip and packing format as much as the roof outline does.
4. Build a template and approve on the vehicle
For a repeatable development, make a paper or foam-board template, mark the datum points and trace the outline. Send a scan, photo or drawing with dimensions. The factory can review the pack and propose a sample, but the target vehicle remains the reference for fit.
On the sample, check edge gaps, clip retention and contact, headroom, operation, removal and storage. Record the approved sample identifier, any outstanding changes and the packaging. Re-check the same points on the production inspection sample.
| Item | What to record | Why it matters |
|---|---|---|
| Roof variant | Model year, trim, market, fixed or opening glass | Separates vehicles that look similar but use different geometry |
| Outline | Width at front, middle and rear; length; datum points | Defines the panel or frame without guessing from a photo |
| Attachment | Clip or frame contact areas, trim gap, sensor clearance | Shows where the shade can sit and what it must not cover |
| Storage | Folded or rolled size, headroom, removal frequency | Sets the construction and packed dimensions |
