What Is a Custom Magnetic Screen Door?
A custom magnetic screen door is a mesh curtain made precisely to the dimensions of your specific door opening. Unlike off-the-shelf screens that come in a handful of standard widths and heights, a custom magnetic fly screen is cut to your exact millimetre measurements - meaning it covers your frame completely with no gaps at the sides, top, or bottom where insects could enter.
The defining feature is the magnetic closure system. Powerful neodymium magnets are sewn into the centre seam of the screen. When you walk through, the two panels part naturally, then snap back together the moment you pass. There are no handles, no latches, and no need to push anything closed. Pets, children, and people carrying bags can all move through without any deliberate action - and the screen seals itself every time.
This is what separates a custom magnetic door screen from older fly-screen alternatives. Retractable screens require frames and can jam. Hinged screen doors need space to swing and hardware to install. Velcro-only mesh panels work but rely entirely on the user remembering to seal the overlap. A custom size magnetic screen door with a magnetic centre seam closes passively, every time, hands-free.
Why Custom Size Matters More Than You Think
The biggest problem with standard magnetic screen doors is fit. Most products on the market come in a small range of preset dimensions - commonly 80×210 cm, 90×210 cm, or 100×220 cm. While these cover a typical interior door, they leave out an enormous range of real-world openings.
French doors, bi-fold openings, sliding patio doors, wider entrance doorways, low-ceiling cottage doorways, and unusually tall modern doors all fall outside those preset sizes. When a magnetic screen custom size option is not available, buyers either struggle with poor fit, cut the screen themselves (often voiding any guarantee), or abandon the product entirely.
A properly fitted custom magnetic fly screen, on the other hand, covers the full opening. There are no gaps at the sides for mosquitoes or flies to enter. The mesh lies flat against the frame, looks clean and intentional, and functions as designed from the day it arrives. For anyone living in a mosquito-prone region, near standing water, or in a country where insect pressure is high, that seal quality is not a luxury - it is the entire point of the product.
Door Openings That Benefit Most from Custom Sizing
Double doors are one of the most common reasons people seek a custom magnetic screen. A standard single-door screen is far too narrow, and two screens placed side by side create a poor seal down the middle. A properly made custom double-door magnetic screen is manufactured as a single wide panel with the magnetic seam positioned exactly at the centre line of the two doors. Both sides close independently and magnetically, creating a complete insect barrier across the full width.
Caravan and motorhome doors are another strong use case. These openings are almost never a standard residential size, and ventilation matters enormously when you are parked in warm climates. A custom screen door made to the exact caravan door dimensions allows fresh air flow without the insects that can make evenings miserable.
Older homes with non-standard proportions, holiday cottages, converted barns, and commercial properties such as cafes or restaurants with open doorways to outdoor seating areas all represent situations where a magnetic screen custom size is the only workable solution.
Custom Magnetic Window Screens: Fresh Air Without the Compromise
The same logic that applies to doors applies equally to windows. Custom magnetic window screens solve a problem that standard insect mesh frames have never fully addressed: windows come in too many shapes and sizes for any preset product to cover them all well.
A custom magnetic window screen is a flat mesh panel with magnets embedded around its entire perimeter. Corresponding magnets or a magnetic strip are attached to the window frame itself. The screen then attaches by simply pressing it against the frame - the magnets hold it firmly in place, it blocks insects completely, and it removes in seconds when you want to clean the window or store the screen in winter.
For homeowners in tropical and subtropical climates, or in countries where window screens are not a standard part of construction, these custom made magnetic window screens represent a significant quality-of-life improvement. You get natural ventilation - the breeze, the sounds, the air - without the mosquitoes, flies, moths, and midges that would otherwise follow.
Because the screen attaches magnetically rather than with adhesive or mechanical fixings, there is no damage to the window frame, no permanent alteration to the property, and no complex removal process. For renters, holiday lets, and anyone who wants a reversible solution, custom size magnetic screen options for windows are an ideal fit.
Magnetic vs Velcro Screen Windows: Which Should You Choose?
When ordering custom screen windows, you will typically have a choice between magnetic attachment and velcro (hook-and-loop) attachment. Both work well, but they suit different frame materials and different preferences.
Magnetic Screen Windows
Magnetic attachment is faster to operate. You press the screen against the frame and it snaps into position. You pull it away and it comes free. The connection is strong enough to stay put in a breeze but easy enough to remove without tools or effort. Magnetic screens work best on frames that have some metal content - aluminium frames, steel casement windows, or any frame where the thin magnetic strip can adhere well and attract cleanly to the screen's edge magnets.
Velcro Screen Windows
Velcro screen windows use a hook-and-loop adhesive strip attached around the window frame perimeter. The screen then presses onto the velcro and holds firmly. This attachment method works on any frame material - timber, uPVC, painted plaster reveals - and tends to create a slightly more airtight seal around the edges. The tradeoff is that attachment and removal takes a little more effort than a magnetic snap. For windows that stay open for long periods during summer, this is rarely a concern. For windows opened and closed multiple times per day, the magnetic option may be more convenient.
Many customers who order both door and window screens choose magnetic doors (for the hands-free closure benefit) and either option for windows depending on frame material.
How to Measure for a Custom Magnetic Screen Door
Accurate measuring is the single most important step in ordering any custom screen door or window. A measurement that is even a few centimetres off can result in a screen that does not seal properly, and because screens are made to order, suppliers typically cannot accept returns for incorrect measurements provided by the customer.
Measuring Your Door Frame
For a magnetic screen door, measure the width of the door opening at three points: near the top, at mid-height, and near the floor. Use the narrowest measurement. Then measure the height on both the left and right sides of the frame, and use the shorter of the two. Measure in millimetres for the highest accuracy. Submit these exact figures when you order - a reputable custom screen manufacturer will cut the screen to precisely what you provide.
If your door frame has a raised threshold (a bar across the bottom), measure to the top of that threshold rather than to the floor. You want the screen to just clear the obstruction so it does not drag.
Measuring for Double Doors
For a custom double door magnetic screen, measure the total combined width of both door panels when open - from the inside left edge of the left frame to the inside right edge of the right frame. The height is measured the same way as a single door. The manufacturer will position the magnetic centre seam at the exact midpoint of the width you provide.
Measuring Your Windows
For custom magnetic window screens or velcro window screens, measure the width and height of the window opening - the space inside the frame that the screen will cover. Measure at multiple points and use the smallest dimension for each. If your window has a handle or winder that protrudes into the frame area, note this when ordering so the manufacturer can advise on the best solution.
What to Look for in a Quality Custom Magnetic Fly Screen
Not all custom screens are made equal. Several quality indicators separate a screen that will last years from one that deteriorates within a season.
Mesh Material
Fiberglass mesh is the gold standard for insect screens. It resists UV degradation, does not corrode, holds its shape under tension, and is easy to clean. Mesh density of 18×16 (18 threads per inch horizontally, 16 vertically) is the standard for general insect exclusion - fine enough to block mosquitoes while maintaining good airflow. Polyester mesh costs less but degrades faster in UV-heavy environments. If you are in a sunny climate, fiberglass is worth the investment.
Magnet Grade
The strength and number of magnets in a custom magnetic door screen determines how reliably it closes and how well it holds against wind pressure. Grade-N52 neodymium magnets are the strongest commercially available grade and provide a firm, satisfying closure. Cheaper screens use weaker magnets that may not fully close in a slight breeze, defeating the purpose of the insect barrier. Look for products that specify magnet grade and pull strength per pair.
Frame and Edge Binding
The edges of the mesh screen need reinforced binding to prevent fraying and to maintain the screen's shape over time. A heavy-duty stitched binding - sewn in multiple passes - will outlast glued or single-stitch alternatives significantly. This is where many budget custom screens fail first: the binding lifts from the corners, the mesh begins to fray, and the screen loses its dimensional accuracy.
Attachment System
For door screens, the adhesive velcro strip that attaches the screen border to the door frame must be strong enough to hold under the repeated snap-force of the magnets without lifting. Industrial-grade pressure-sensitive adhesive, applied to a clean dry surface, should hold for years without residue when removed. Check that the manufacturer includes full-width adhesive strips - not just short patches at intervals.
Custom Magnetic Screens vs Standard Off-the-Shelf Options
Products like Magic Mesh and other standard-size magnetic screen doors are widely available and appeal on price. For a door that happens to match a standard dimension, they can work acceptably. The limitations become clear quickly, however, when your opening does not match the preset size - which is more often the case than not.
Magic Mesh custom sizes are not offered by most standard retailers, which is precisely why the demand for made-to-measure alternatives has grown substantially. When a standard 36-inch door screen is fitted on a 34-inch or 38-inch opening, the result is either a screen that billows inward and does not seal, or one pulled so tight it stresses the attachment points and lifts from the frame within weeks.
Beyond fit, custom made magnetic screen doors are typically made from higher-grade components. The mesh is heavier, the magnets are stronger, the binding is reinforced. Because a custom manufacturer is selling a precision product rather than a commodity, the quality bar tends to be meaningfully higher - and the finished screen looks and feels more like a permanent home improvement and less like a temporary fix.
Installation: Easier Than You Expect
One of the most common hesitations before ordering a custom magnetic screen door is the assumption that installation will be complicated. In practice, a well-made custom screen installs in under 15 minutes with no tools required.
The process involves cleaning and drying the door frame surface, applying the adhesive velcro strip around the perimeter of the opening, pressing the screen's binding against the velcro, and hanging the top header strip. The screen then hangs naturally in position, the magnets align, and the installation is complete. Most customers are surprised at how fast and simple the process is - and equally surprised at how professional the finished result looks.
For custom magnetic window screens, installation is even simpler. The magnetic strip adheres to the window frame perimeter, the screen is pressed against it, and the job is done. Removal for window cleaning or seasonal storage takes seconds.
Who Benefits Most from a Custom Magnetic Screen?
Custom magnetic fly screens are bought by a wide range of people for a wide range of reasons. Homeowners in mosquito-prone regions - Southeast Asia, Australia, the Mediterranean, Florida, and similar climates - represent the core market. Holiday rental owners who want to improve guest comfort without structural modifications are another major group. Pet owners who want their dogs or cats to move freely between indoors and outdoors without constantly opening and closing a door appreciate the hands-free closure. Families with young children value the same thing.
Restaurants, cafes, and commercial properties with outdoor areas also use custom magnetic door screens to maintain an open, welcoming entrance while controlling insect access to kitchen and dining areas. Because the screens install without permanent fixings, they are suitable for leased commercial premises as well as owned properties.
If you live somewhere with warm summers, strong insect pressure, or simply want to keep your doors and windows open without the consequences, a custom size magnetic screen door or window screen is one of the most practical, affordable, and reversible improvements you can make to your home.
