Replacement Golf Impact Screen for an Existing Enclosure: How to Measure, Match, and Order the Right Size

Four inches. Carl's Place says your enclosure's frame opening should be about that much wider than the screen hanging inside it, which works out to roughly 2 inches of room on each side for the bungees (Source: Carl's Place FAQ, via Golf Simulator Forum). Get that wrong and a brand-new screen either sags like a hammock or gets pulled so tight it fires balls back at your shins.

If you're shopping for a replacement golf impact screen for an existing enclosure, that gap decides whether the swap works. Your frame is already built and it isn't moving, so the screen has to fit the frame.

This guide covers how to measure the opening, how much gap and tension to leave, how to match grommets to your attachment points, and how to tell whether a standard size will work or you need a custom one.

Why a Replacement Golf Impact Screen Beats Buying a Whole New Enclosure

Screens wear out long before frames do. Ball marks pile up, a mishit catches the edge, or years of tension stretch the fabric until it bags in the middle. The steel or EMT pipe around it is usually fine.

When you swap only the screen, your projector alignment, side netting, and mat position stay exactly where you set them. You replace the one part that takes every impact and leave everything else alone.

The catch is that the new screen has to fit a frame you may not have designed. Maybe it came in a kit, or maybe you built it yourself three years ago and lost the notes. Either way, you start with a tape measure.

Step 1: How to Measure Your Enclosure Frame for a Replacement Screen

Measure the inside of the opening, not the outside

What you need is the clear space between the frame members: inside edge of the left upright to inside edge of the right, and underside of the top bar down to the bottom rail or floor. Outside measurements include the pipe thickness, which can throw you off by 2 or 3 inches.

Measure in three places

Measure the width at the top, middle, and bottom, and the height at the left, center, and right. Frames drift out of square, especially DIY builds and anything that's been knocked a few hundred times. Use the smallest number in each direction.

Write down your attachment points and back clearance

While you're up there, note every place the frame lets you tie off: pre-drilled holes, eye bolts, hooks, a bottom pipe. You'll need that list in Step 2. Also check the space behind the screen. You want at least 12 inches between the screen and the back wall, because less than that causes noise and bounce-back (Source: My Golf Simulator).

What the Data Says About Screen-to-Frame Gap

Once you have the opening size, subtract the gap. This is the step people worry about, because the sources don't all give the same number. For bungee mounting, though, they land in a fairly narrow range.

• Carl's Place: about 2 inches between each side of the screen and the frame, so the opening is roughly 4 inches wider than the screen overall (Source: Carl's Place FAQ, via Golf Simulator Forum).
• Golfbays: 5 to 7.5 cm (about 2 to 3 inches) on the left and right. For tension, you should be able to push your hand about 25 cm (roughly 10 inches) into the center of the screen (Source: Golfbays Impact Screen FAQs & Guidance).
• DIY frame builds: a roomier 6 to 12 inches of clearance on all sides, with 12 to 18 inches of air gap behind. The example is a 10×9 ft screen in a frame built to 11 ft wide by 10 ft tall (Source: GolfingSim DIY frame guide).

The hand-push test is the most useful number on that list. If the screen won't give about 10 inches, it's too tight, and that's what causes bounce-back and torn grommets. If it gives a lot more than that, the fabric will ripple and blur your image.

So what gap should you plan for?

For most pre-built enclosures that use ball bungees, plan on 2 to 4 inches per side. With a 10 ft wide opening, that means a screen between about 9 ft 4 in and 9 ft 8 in wide. Do the same math on the height, and make sure the top bungees have room. If you use tarp clips or longer bungees, go toward the bigger end. Forum users report going to about 6 inches per side with tarp clips (Source: Golf Simulator Forum).

Step 2: Match the Attachment Style to Your Frame

A screen can be the right size and still be the wrong screen if its grommets don't line up with your frame. Go back to the attachment-point list from Step 1.

Grommets and ball bungees

This is the most common setup and the easiest to get right. Carl's Place screens use grommets with a 3/4 in outer and 3/8 in inner diameter, set in a 2.5 in black vinyl edge, and they hang on 6-inch or 9-inch ball bungees (Source: Carl's Place and Indoor Golf Outlet).

Bungee length affects your gap. According to Carl's Place, the 9-inch bungees let the screen hang looser, which reduces bounce-back (Source: Carl's Place). If your old screen had a wide gap and long bungees, use long bungees on the new one too. Our grommet vs bungee attachment breakdown covers which edge systems hang flattest.

Loop fasteners and flaps

Some enclosures are designed for a loop-fastener or flap edge instead of plain grommets. Carl's Place Standard screens come in those edge finishes as well, so order the edge your frame already expects instead of adding new hardware.

Sleeves, chain, and odd grommet layouts

Custom is the right call if your frame weights the screen with a bottom pipe or chain, or if your attachment points don't match a standard grommet layout. Custom replacement screens can be made up to 20 ft high by 25 ft wide. The default is a grommet every 6 inches along the top, one in each bottom corner, and one centered on each side, and you can add grommets or a bottom sleeve for 1/2 in chain or 3/4 in pipe (Source: AHH.biz).

Standard or Custom Replacement Impact Screen for Your Existing Enclosure?

Check standard sizes first. Carl's Place Standard screens come in four aspect ratios (1:1, 4:3, 16:10, and 16:9) with heights from 7.7 ft to 10 ft, and custom sizes are available on request (Source: Indoor Golf Outlet). If your opening minus the gap is close to one of those preset sizes, a standard screen will almost always cost less than a custom one.

Make sure the aspect ratio matches your projector too. If you're replacing a 4:3 screen and you've since moved to a 16:10 projector, now is the time to fix it. Our impact screen aspect ratio guide explains why the wrong match wastes screen space.

Edge finish changes the price more than most people expect. At 10×10 ft, a flap edge costs noticeably more than grommets only, and a premium-tier screen from another brand costs almost twice as much as the grommet-only Standard. Prices change, so check the current price before you order.

If you hit a lot of drivers and want more durability or a sharper image than Standard gives you, read our Carl's Place Standard vs Preferred vs Premium comparison before you buy.

Your Replacement Screen Checklist

1. Measure the inside width and height of the opening in three spots each, and use the smallest number.
2. Subtract your gap: about 4 inches total for standard bungee mounting, more for tarp clips or long bungees.
3. Make sure there's at least 12 inches of air gap behind the screen.
4. List your frame's attachment points and pick the matching edge: grommets, loop fastener, or flaps.
5. Match the aspect ratio to your projector.
6. If your numbers are close to a preset size, go standard. If they aren't, or your attachment points are unusual, go custom.
7. After hanging it, do the hand test: you should get about 10 inches of give in the center.

Ready to Swap Your Screen?

The frame is already built, so the swap is mostly measuring. Measure twice, choose your gap, and match the edge to your frame, and the new screen will hang like it came with the enclosure. Browse Carl's Place impact screens at GolfingSim to pick your size, ratio, and edge finish. If your opening doesn't match a preset size, ask us about a custom screen.
