Ideally a few sizes larger, to allow yourself a few attempts if you get it wrong. …and of course a bit of screen protector film larger than the screen you want to protect. You’ll need: A sharp scalpel (or paper guillotine), a metal ruler (or paper guillotine) and a fine tipped marker pen – like a Sharpie (or paper guile… no, just kidding – but you will actually need a Sharpie).

Let’s look at how you’d go about cutting a protector down to size. That being said, sometimes you’d like one for an older camera, or a rarer device that’s lesser known – and for these devices it can be a nightmare to find the correct sized screen guard for it. I never recommend customers cutting one of ours to fit, instead I’d much rather they buy their correct size from someone else (if we don’t stock their model already, that is) so that they end up with the perfect fit – than ham-handedly butcher one themselves. Now generally it’s a bad idea to cut your own protector to fit. If this isn’t the case, just get in touch with the retailer you bought your screen protector from and (if you ask nicely) they might just send you a replacement to try again.

If you do have any bubbles still, you should be able to remove them with the sticky tape technique. That’s it! You’re now looking at what a nicely fitted protector should be like. Once you’ve finished, carefully peel off the final ‘Step 2’ layer – being careful to make sure you don’t peel the actual screen protector with it. The best way to do this is with a credit card wrapped in the cloth you received with your protector. Once you’ve discarded the ‘Step 1’ layer, just chase out any remaining bubbles.Now slide your finger along the screen, while peeling off the remainder of the ‘Step 1’ layer. If the protector you have is a good one, it will just chase out the bubbles without much effort. Now align the exposed edge with that edge of your screen, and begin to push it down and chase out the bubbles. Peel back about 1 inch of the ‘Step 1’ layer to expose the gel-like sticky side underneath, you want to make sure this freshly exposed side isn’t left exposed for very long as dust can settle on it.Only once you’re sure there’s not a speck on there, can you begin to fit the screen guard. Don’t just rely on giving it a wipe down with the cloth, reflect some light off the screen so you can pick up any specks of dust. This is the single most important task, just making sure there’s not a single speck of dust on the screen before you begin. Slide it around to see how much room for error you may have at the edges, or if the bezel is particularly unusual. Before cleaning the screen, it’s a good idea to lay the protector on your LCD to get a feel for how it aligns.Failing that, the kitchen with the kettle on.

It doesn’t need to be super steamy, just a little will do.

The moisture in the air settles any dust. The ideal environment is in the bathroom, just after steam has settled from a hot shower or bath. Ideally without wearing a massive woolly jumper either.

You want to get yourself into an area with as little movement around you as possible.

And the cause of bubbles? Well, if you can’t just push them out to the edges, then they’re nearly always caused by dust. Sure there can be other problems, but mostly its bubbles.

The biggest problem with fitting a protector is bubbles.

Here I’m going to run through a fail-safe guide, with some helpful tips for a stress-free application. You can apply a screen protector to your camera’s LCD screen in minutes, without bubbles, without hassle.
