Windproof Roller Blind Sizes: How to Match a Model to Your Opening
Compare size ranges, motor torque ratings, and drop limits across 8 windproof roller blind models spanning from 0.65 m up to 14 m wide for outdoor openings.
Matching a windproof roller blind to an exterior architectural opening requires aligning measured structural width and drop against the operational envelope and motor class of each model. Because zip-track systems hold the fabric edges inside fixed aluminium side tracks, units are made to the measured opening rather than trimmed on site, which makes dimensional planning the first step.
Exterior shading installations across patios, pergolas, balconies, and outdoor dining areas present diverse structural conditions. A compact balcony aperture measuring 2.6 m wide requires a very different mechanical assembly than an expansive commercial terrace spanning up to 14 m. The model choice is what ties the opening dimensions to the motor class, the fabric and the stated wind rating.
This sizing guide provides distributors, engineering contractors, and project buyers with the technical parameters needed to match exterior openings to the eight windproof roller blind models supplied by eziptrack.
Why the Opening Size Decides the Model
On a standard drop or cable-guided system, the fabric edges stay unguided. On a zip-track windproof roller blind, zipper teeth are welded along both vertical edges of the composite fabric and travel inside the aluminium side channels along the full drop. Because the fabric runs inside fixed side tracks, each blind is made to the measured opening rather than adjusted on site.
Four dimensions drive this selection:
- Width: sets which model envelopes fit, from 0.65 m on the ZT90 up to 14 m on the ZT180.
- Drop: sets the height limit for the model, from 2.5 m on the ZT90 up to 7 m on the ZT180.
- Motor class: the wider models pair with the higher motor ratings, from 10 Nm up to 20 N.
- Fabric roll width: the catalogue lists four roll widths (200 cm, 250 cm, 300 cm and 320 cm).
Before selecting a model, opening dimensions must be recorded. According to the eziptrack measuring method, three width points (W1 at the top, W2 at the middle, and W3 at the bottom) and three height points (H1 at the left, H2 at the centre, and H3 at the right) must be recorded.
For an inside recess installation, the guide uses the smallest of the width readings, with product width at
WP = WW − 5 mm and height at HP = HW (or HW − 5 mm). For an outside or ceiling installation, width still uses the smallest reading (WP = WW + 4", and the guide notes the 4" can be adjusted to suit the site), while height uses the largest reading: HP = HW + 6–8".Once confirmed structural opening dimensions are established, buyers can navigate the product range to identify the corresponding size envelope.

Reading the Size Envelope: Span, Drop and Motor Torque
A sizing envelope is more than a geometric boundary: within each model, the casing, the fabric and the motor are matched to one another.
When evaluating the specifications of the motorized range, buyers will observe a clear progression in motor ratings corresponding to physical dimensions:
- 10 Nm class (AG40RE-10/14, 110–230 V AC): ZT90 and ZT110.
- 15 Nm class (AG50RM, 110–230 V AC): ZT150.
- 15 N class (AM45, 110–230 V AC): Double Layer.
- 20 N class (AM45, 110–240 V AC): ZT170 2-in-1 and ZT180.
A larger opening carries more fabric than a compact one. The composite fabric used in eziptrack systems—such as the PW100 series composed of 30% polyester and 70% PVC—carries a stated surface density of 565 g/m² (±5%) and a thickness of 0.70 mm (±5%). The wider models pair with the higher motor classes.
All tubular motors across the motorized product line share documented operational standards:
- Continuous Operating Duty: Rated at S4 min continuous operating time.
- Operating Temperature Range: Rated from -10 °C to +60 °C for diverse climate conditions.
- Control Methods: Remote control or Wi-Fi through the TUYA app.
- Voltage Compatibility: Configured for 110–230 V AC or 110–240 V AC supply, accommodating international electrical infrastructure.
What Changes as Openings Get Wider
When an architectural opening expands beyond standard window widths into expansive patio, terrace, or facade spans, several physical parameters change simultaneously. Understanding these factors helps project planners select between mid-span models like the ZT150 and heavy-span models like the ZT180.
Roll Widths and Fabric Panel Layout
Exterior zip-track blinds utilize composite screen fabrics manufactured in standard roll widths. The fabric catalogue lists four roll widths:
- 200 cm roll width
- 250 cm roll width
- 300 cm roll width
- 320 cm roll width
When planning a wide opening, confirm the fabric panel layout for the specific model and size with the team.
Stated fabric tear strength is warp ≥2,650 N/5 cm and weft ≥2,450 N/5 cm. The fabric also carries a stated B1 fire-retardant classification and a stated ISO 105 B02 Grade 8 colour fastness to light (a light-fastness measure, a different scale from the wind grades).
Structural Profiles Across the Range
Wide-span systems hold the fabric edges along the full drop through the welded zipper edge running inside each aluminium side track, the same side-retention system used across the range.
As openings widen to 5 m on the ZT150 or up to 14 m on the ZT180:
- The casing is a one-piece aluminium alloy shell with no visible seams on the face, stated to resist impact and corrosion.
- Track and bottom rail are aluminium alloy across the range.
- The wider models carry the higher motor classes: 15 Nm on the ZT150 and 20 N on the ZT170 and ZT180.
If the width exceeds 5 m, or the drop exceeds 5 m, the ZT180 is the model that covers it: up to 14 m wide and 7 m high, with a manufacturer-stated windproof grade 8.
Manual Models and Their Own Size Ranges
Where an opening has no electrical supply, the range includes two manual windproof roller blind models.
Manual models operate under distinct sizing parameters that differ from the motorized product line:
- Width Range: 500 mm to 4000 mm.
- Height Range: 1500 mm to 3000 mm.
- Operation: Hand rocker control.
- Fabric Categories: Shading and light-transmission fabric categories.
- Casing and Track Colours: Dark grey, white, coffee.
- Component Material: Aluminium alloy side tracks and bottom rail.
- Wind Performance: Manufacturer-stated windproof grade 10.
- Sizing Characteristic: The Hand Crank model has the narrowest minimum width in the range, at 500 mm.
- Width Range: 1200 mm to 4000 mm.
- Height Range: Up to 3000 mm (specified from 0 to 3000 mm drop).
- Operation: Wireless spring; the blind is positioned by hand from the bottom rail.
- Fabric Categories: Shading and light-transmission fabric categories.
- Casing and Track Colours: Dark grey, white, coffee.
- Component Material: Aluminium alloy side tracks and bottom rail.
- Wind Performance: Manufacturer-stated windproof grade 10.
- Sizing Characteristic: The minimum width for the Cordless Spring System is 1200 mm.
Both manual models share a maximum width limit of 4000 mm and a maximum drop limit of 3000 mm. Both carry a manufacturer-stated windproof grade 10 rating. Openings wider than 4000 mm or taller than 3000 mm fall outside the manual models’ listed ranges; the motorized models cover larger spans.
Sizing FAQs
What is the maximum opening size available in a single windproof roller blind?
The largest single unit in the range is 14 m wide by 7 m drop, on the ZT180 large-size motorized windproof roller blind. It uses the AM45 motor (20 N, 110–240 V AC) and carries a manufacturer-stated windproof grade 8.
What if the opening width falls between two model ranges?
Where two models overlap in width—for example between 0.68 m and 2.6 m, which both the ZT90 and ZT110 cover—compare the drop. If the drop is over 2.5 m (up to 3.2 m), the ZT110 covers it; at 2.5 m or less, both models fit the width. Take the three-point measurements, then send the opening to the team to confirm the configuration.
Do manual windproof roller blinds share the same size envelopes as motorized models?
No. Manual zip-track roller blinds operate within their own dimensional ranges. The Hand Crank model spans widths from 500 mm to 4000 mm with drops from 1500 mm to 3000 mm, while the Cordless Spring System spans widths from 1200 mm to 4000 mm with drops up to 3000 mm. For openings outside those ranges, the motorized models start at 0.65 m wide (ZT90) and reach 14 m wide by 7 m high (ZT180); anything beyond those envelopes is outside the listed models and needs confirmation with the team.
Which models offer blackout fabric?
Blackout fabric is listed as available across the motorized models: ZT90, ZT110, ZT150, ZT170 2-in-1, ZT180 and the Double Layer blind (the blackout series include PW200 at 420 g/m² and PW600 at 650 g/m²). Blackout fabric blocks all light and both sightlines. The manual models (Hand Crank and Cordless Spring) are catalogued with shading and light-transmission fabric categories.
What should be included in an opening schedule?
To specify a model and receive an accurate quotation, buyers must record three horizontal width points (W1 top, W2 middle, W3 bottom) and three vertical height points (H1 left, H2 centre, H3 right). For inside recess mounting, take the minimum width and subtract 5 mm (
WP = WW − 5 mm). For outside face mounting, width uses the smallest reading (WP = WW + 4") and height the largest (HP = HW + 6–8"). Provide these dimensions alongside your preferred fabric openness rate (from 1% up to 30%, or blackout) and frame colour.Match the Model to the Opening
Selecting the right windproof roller blind model begins with verified opening dimensions. Whether your project involves standard residential patio bays, specialized dual-layer balcony screening, or expansive commercial hospitality spans up to 14 m, matching the aperture width and drop to the correct size envelope and motor class is how the model is chosen.
Send us the width and height of each opening, the preferred fabric transmittance and frame colour, and our team will confirm the configuration and provide a quotation. Projects with multiple windows or whole-house shading schedules are welcome. The site lists a shipment lead time of 7–15 days.
