WriteRight Screen protectors. I buy a pack and have them at hand whenever I need to make a new screen protector or replace an existing one. The size it comes in is just right and there are grids printed onto them for better measurement. Here are the tools you’ll need: Tools Screen protector Blank white paper/cutting board (substitute a cutting board for plain white paper) Ruler Paper cutter Let’s get started: 1. Place the screen protector against the screen of the gadget. 2. Measure the dimension of the screen’s area against the grid on the screen protector. 3. Place the screen protector on a white blank paper, place a ruler to make sure you cut in a straight line, then use a paper cutter to cut the area you’ve marked. 4. If you’re unsure, place the screen protector against your gadget’s screen to make sure it is the right measurement. Remember which numbers your screens’ edges fall between. 5. Clean your screen before you place the protector on. That’s the key in avoiding bumps and achieving a smooth finish. 6. As soon as you’ve gotten your perfectly measured rectangle, you can carefully apply the screen protector to your screen using your thumb to smooth it out as you apply. This is the hardest step. 7. Voila! No more scratches or chips on that beautiful screen.
