To measure for a retractable screen door, measure the width and height of your door frame’s inside opening (from jamb to jamb, and threshold to top). Take measurements in three spots each and use the smallest value to ensure a snug, accurate fit.
Getting the perfect fit for your retractable screen door starts with precision. A door that’s even slightly off-size can affect its smooth retraction, sealing, and overall lifespan. Let’s go step by step so you can measure confidently, whether you’re installing it yourself or ordering from a professional manufacturer like Oridow.
What Is a Retractable Screen Door, and Why Does Accurate Measurement Matter?
A retractable screen door rolls or slides into a slim housing when not in use, disappearing. Unlike fixed screens, these doors are designed for flexibility and style, but they rely on perfect alignment.
If your measurements are off by even half an inch, you might face:
- Gaps that let insects in
- Screens that don’t retract smoothly
- Misalignment that wears out the track or mesh prematurely
Accurate measurement = long-lasting performance.
How Do You Measure a Retractable Screen Door Opening?
Here’s a step-by-step guide you can follow with just a tape measure and a notepad.
1. Measure the Width
- Measure from jamb to jamb (inside frame) at three points: top, middle, and bottom.
- Record all three values and use the smallest width. This ensures your screen fits even if the frame isn’t perfectly square.
2. Measure the Height
- Measure from the bottom threshold to the top inside edge of the frame on both the left and right sides.
- Again, use the shorter height if the values differ.
3. Check Frame Squareness
- Measure both diagonals of the opening.
- If they differ by more than ¼ inch, your door may need shimming or adjustment during installation.
4. Note Any Trim, Handles, or Obstructions
- Look for door handles, floor mats, or decorative trims that might interfere with the track or housing.
- Note these details when ordering. Custom retractable screen doors like those from Oridow can be tailored to avoid obstructions.
What Tools Do You Need to Measure for a Retractable Screen Door?
You only need a few simple tools:
- Tape measure (metal, not cloth)
- Level (to check squareness)
- Pencil and notepad to record dimensions
- Helper (optional but handy) for wider openings like French or double doors
Pro tip: Use inches and fractions, not rounded centimeters. Precision makes installation smoother.
If your screen tends to drag or feel uneven later, regular screen cleaning can help keep it sliding properly.
Should You Measure for a Single or Double Retractable Screen Door?
It depends on your door type:
| Door Type | Recommended Screen Style |
| Standard single door | Single retractable screen |
| French doors or patio sliders | Double retractable screen (meeting in the middle) |
| Large custom openings | Oversized dual screen systems |
If you’re unsure, take measurements for both panels and share them with your supplier. Oridow’s design team reviews measurements before confirming orders to ensure accuracy.
What If Your Door Frame Isn’t Standard Size?
That’s common, especially in older homes or custom builds.
If your measurements don’t match standard sizes, consider:
- Custom retractable screen doors made to fit your exact opening
- Adjustable cassette systems that allow a small range of flexibility
- Professional measurement services (many suppliers, including Oridow, offer this)
Custom fitting ensures your screen sits flush, operates smoothly, and looks seamless.
Common Mistakes to Avoid When Measuring
- Measuring the wrong surface. Always measure the inside of the frame, not the outer trim.
- Rounding up measurements. Always round down to the nearest 1/16 inch.
- Ignoring uneven floors or warped frames. Note any visible tilt.
- Not checking both sides. Even small differences matter for retractable tracks.
Avoiding these ensures your installation is quick, clean, and frustration-free. If you ever notice issues afterward, refer to Oridow’s repair guide for easy fixes.
How Do Professionals Measure Retractable Screen Doors?
Industry pros typically:
- Use laser measurement tools for precision
- Verify plumb, level, and square before taking the final numbers
- Confirm measurements with the manufacturer before fabrication
According to installation data from screen manufacturers, up to 70% of installation issues stem from incorrect measurements, not product defects.
Taking your time here saves you from returns or rework later.
Quick Measurement Checklist
- Measure width (top, middle, bottom)
- Measure height (left and right)
- Record the smallest width and height
- Check squareness
- Note obstructions (handles, trim)
- Confirm if single or double door
Final Thoughts

FAQs About Measuring Retractable Screen Doors
How do I know if my door frame is square?
Measure both diagonals of the door opening. If the difference is more than ¼ inch, the frame isn’t square, and you may need shimming during installation.
Do I measure inside or outside the door frame?
Always measure inside the frame (jamb to jamb). That’s where the retractable screen mounts.
What if my measurements fall between standard sizes?
Choose the smaller size or opt for a custom-built screen. A slightly smaller screen ensures a tight fit.
Can I install a retractable screen door myself?
Yes. Most modern retractable screens come with DIY-friendly kits. Just ensure your measurements are precise before ordering.
Should I remove my old screen before measuring?
Yes. Remove any existing fixed or magnetic screens to measure the actual frame dimensions.
