Size Guide

Size Guide

To help you choose the right size and quantity, please refer to the following common window types and matching film sizes:

  • Double-Hung Window (24" × 36")
    For standard double-hung windows, we recommend purchasing 2 rolls of Size A (23.6" × 35.4").
    This allows you to cover both the upper and lower panels separately, ensuring a clean and precise fit.
  • Casement Window (35" × 78")
    For tall casement windows that open outward, we recommend 2 rolls of Size B (17.32" × 78.74").
    Each roll can be applied to one side of the window for full vertical coverage.
  • Sliding Window (35" × 78")
    Sliding windows typically consist of two horizontal panels. We suggest 2 rolls of Size B (17.32" × 78.74") to cover each panel individually while maintaining alignment and ease of installation.
  • Narrow Lite Window (14" × 78")
    For narrow vertical windows, only 1 roll of Size B (17.32" × 78.74") is needed.
    The extra width allows for easy trimming to achieve a perfect fit.

Warm Tips:

  • Always measure your glass area (not the frame) before purchasing.
  • Choose a slightly larger size to allow trimming for a seamless installation.
  • If your window size differs from the examples above, you can combine multiple rolls or cut the film to fit your exact dimensions.
