1. Car model and body area
Different car models have different sizes. Large vehicles such as SUVs and MPVs require more film materials than sedans. For example, the body area of ​​a compact sedan is about 18-22㎡, while a full-size SUV may reach 25-30㎡.
Film coverage: The amount of film used for the whole car (including the roof, front and rear bumpers) and partial film (only the hood, doors, etc.) is significantly different.

2. Film width and construction method
The common film width is 1.52 meters (60 inches). If the width of the body part exceeds the width of the film material, it needs to be spliced ​​or the cutting method needs to be adjusted.
Construction technology affects the proportion of scraps: skilled technicians can reduce waste through reasonable layout, and novices may increase losses due to cutting errors.

3. Film type and ductilityTPU invisible car cover has better ductility, and can cover complex curved surfaces by stretching to reduce seams;
Color-changing film (such as PVC material) has poor ductility, and more margin is required for complex parts (such as rearview mirrors and bumpers).
