Why Measurement Matters for Your Custom Screen Door?
Standard magnetic screen door sizes don't exist in every home. Older houses, custom-built properties, and even newer construction can have measurements that fall outside anything you'll find in a hardware store. A custom magnetic screen door that's even 1 inch too small will leave gaps; one that's too large will sag or bow. A precise fit magnetic screen is designed to hug your frame perfectly—but that precision depends entirely on you.
Tools You'll Need
Metal measuring tape (not fabric, which can stretch)
Pencil and paper
A helper (for large doors and windows)
Step stool (for high windows)
Step-by-Step: How to Measure Your Door Frame
Step 1: Measure the Width
Measure the width of your door frame in three places: top, middle, and bottom. Record all three numbers. Use the smallest measurement as your baseline—this ensures your magnetic screen door won't be too tight anywhere on the frame.
Step 2: Measure the Height
Measure the height on the left side, center, and right side. Again, use the smallest measurement to account for any slight unevenness in your frame.
Step 3: Account for Frame Depth
Most door frames have some depth (the thickness of your door). Measure from the front edge to the back edge of your frame. Most magnetic screen doors work best with frames that have at least 1 inch of depth, though Zoormesh products are designed to accommodate a range of depths with their adhesive mounting system.
Step 4: Check for Obstacles
Look for anything that might interfere with your custom screen door: door handles, locks, mail slots, or decorative molding. Note their positions and measure around them.
Step 5: Double-Check and Use the Online Configurator
Run through your numbers twice. When in doubt, round up very slightly (no more than ¼ inch) rather than rounding down. Zoormesh's online screen door configurator lets you enter your measurements and see exactly how your custom magnetic screen door will look before you order—take advantage of this to avoid costly mistakes.
Common Mistakes When Measuring for a Custom Magnetic Screen Door
Measuring the glass portion only (include the frame!)
Using an old fabric tape measure that has stretched
Rounding to the nearest whole number instead of the nearest fraction
Forgetting to measure depth, which affects how the magnetic screen sits against the frame
Not measuring French doors or sliding glass doors as separate panels
Measuring Specific Door Types
French Doors (Magnetic Screen for French Doors)
French doors require measuring each panel individually. Record the width and height of each door panel. Also measure the gap between the two doors—this is critical for the magnetic center seam of your custom magnetic screen door.
Sliding Glass Doors (Sliding Glass Door Magnetic Mesh)
Sliding glass doors often have deeper frames. Make sure to measure the depth carefully. Also measure the height of the track—the bottom rail needs clearance for the magnetic screen door to sit properly.
Large Patio Doors (Large Patio Door Screen Solutions)
For oversized patio doors, measure at multiple points across the width. Wide openings are more prone to slight variations in measurement. Use the smallest measurement and trust the precision of a custom screen door by dimensions.
RV and Camper Doors (RV & Camper Custom Screen Door)
RV and camper doors are rarely standard sizes. Measure carefully and note any curved or irregular frame shapes. Zoormesh's custom screen door by dimensions handles non-standard RV openings perfectly.
