Magnetic Garage Door Screen: Best Options & How to Install

A garage is one of the most useful spaces in a home — workshop, gym, storage, hobby room. The problem is that an open garage door invites every flying insect in the neighbourhood. A magnetic garage door screen solves this: you get full airflow and daylight with a mesh barrier that closes automatically behind you.

Why Garage Door Screens Are Different

A standard garage door opening is significantly larger than a regular door — typically 8–10 feet wide and 7–8 feet tall for a single car, up to 16 feet wide for a double. This creates challenges that standard door screens don't face:

Size. No off-the-shelf magnetic door screen covers a 10-foot opening. Garage door screens need to be purpose-made for the size.

Weight. A screen that large needs heavier mesh and more robust attachment to stay in place without sagging.

Entry points. Garage door screens typically use a center seam closure (like standard door screens) but need more magnets and a stronger seam to close reliably across a wider span.

Drive-through use. Some garage screens are designed to allow cars to pass through; others are walk-through only. Know which you need before buying.

Best Magnetic Garage Door Screen Options

CoverWith Custom — Best for Non-Standard Sizes

CoverWith makes custom magnetic screens to exact measurements, including garage door openings. For garages with non-standard dimensions or anyone who wants a precise fit without edge gaps, this is the right option. The fiberglass mesh and industrial hook-and-loop attachment handle the larger format well.

For a standard single-car garage (9' × 7'), a custom CoverWith screen provides full coverage with no gaps at the edges — the main failure point of generic garage screens.

Best for: Non-standard garage sizes, anyone who needs a guaranteed fit.

Garage Door Screens (Purpose-Built Double-Panel)

Several brands make purpose-built garage door screens in standard garage sizes. These typically use two wide panels with a center zipper or magnetic closure and a top header that attaches across the garage door opening.

Key features to look for:

• Fiberglass or polyester mesh rated for outdoor use
• Weighted bottom hem to prevent billowing
• Walk-through zipper or magnetic center seam
• Attachment system compatible with your garage door frame

Standard sizes: 10' × 7' (single), 16' × 7' (double). Measure your opening before ordering — garage door dimensions vary.

Typical price range: $40–80 for standard sizes.

DIY Two-Panel Approach

Some homeowners use two standard magnetic door screens side by side to cover a single-car garage opening. This works with caveats: the screens need to be mounted at the same height, the center seams of each screen need to align with each other, and there will be a gap where the two screens meet.

For workshop or hobby use where occasional insect entry is tolerable, this is an inexpensive option. For serious bug exclusion, a purpose-built solution works better.

How to Install a Magnetic Garage Door Screen

What You'll Need

• The screen kit (usually includes header bar, side rails or tape, and the mesh panels)
• Measuring tape
• Drill (for header bar installation)
• Level
• Isopropyl alcohol for surface prep

Installation Steps

Step 1 – Measure the opening. Measure the width and height of your garage door opening — the space inside the frame, not the door itself. Standard single-car: 9–10' wide × 7' tall. Standard double: 16–18' wide × 7' tall.

Step 2 – Clean the frame. Wipe the top and sides of the garage door frame with isopropyl alcohol. Dust, grease, and paint residue prevent adhesive from bonding. Allow to dry fully.

Step 3 – Attach the header. Most garage door screen kits include a header bar that spans the top of the opening. Drill into the frame at the top, level the bar, and secure it. This is the primary load-bearing point — get it level or the screen will hang crooked.

Step 4 – Hang the panels. Attach the mesh panels to the header and press the side edges against the frame using hook-and-loop tape or the included clips. Work from top to bottom, keeping the mesh taut.

Step 5 – Weight the bottom. Garage door screens need a weighted hem at the bottom or a ground attachment to prevent billowing. Press the bottom edge against the floor threshold or attach a ground anchor if included.

Step 6 – Test the center closure. Walk through the center seam and confirm it closes fully behind you. Check all four edges for gaps.

Tips for Getting More Life from a Garage Screen

Remove it in winter. Magnetic garage screens aren't designed for cold weather or snow load. Take it down before temperatures drop and store it flat.

Reinforce the header attachment. The header takes the most stress. Check the screws or anchor points every few months and tighten as needed.

Clean the mesh periodically. Garage environments are dusty. A clogged mesh restricts airflow and puts more stress on the attachment points. Hose it down or vacuum it lightly every few months.

FAQ

Can you put a screen on a garage door? Yes. Purpose-built garage door screens attach to the door frame and cover the opening when the garage door is raised. They don't attach to the door itself.

What size garage door screen do I need? Measure the width and height of your garage opening. Standard single-car openings are 9–10 feet wide × 7 feet tall. Double garages run 16–18 feet wide. Order a screen that matches your measurement.

Do magnetic garage door screens keep mosquitoes out? Yes, when properly fitted. The main entry points are edge gaps and the center seam. A well-fitted screen with a fully closing center seam keeps mosquitoes and most flying insects out effectively.

Can a car drive through a garage door screen? Some garage door screens include a drive-through zipper designed to open fully for vehicles. Standard walk-through screens are not designed for car access and will be damaged if driven through.

How do I stop a garage screen from blowing in the wind? A weighted bottom hem and ground attachment are the most effective solutions. Some screens include tie-down straps that anchor the sides to the garage floor.

Final Thoughts

A magnetic garage door screen converts your garage into a usable, ventilated space during warmer months without the insect problem. For standard garage sizes, purpose-built two-panel screens offer good coverage at a reasonable price. For non-standard openings or anyone who needs a precise fit, CoverWith's custom option handles the sizing cleanly. Install the header bar carefully, prep the frame surface properly, and weight the bottom — those three things determine whether a garage screen works well or poorly.
