What Is My Screen Resolution

About This Tool

Ever opened a website and thought, “Why does this look so weird on my screen?” Or maybe you're trying to set up a new monitor and just want to know what resolution you're actually working with. That’s where this tool comes in. It’s simple: it tells you your screen resolution—no fluff, no login, no nonsense.

I built this because I got tired of guessing. One day I was resizing a window and realized I had no clue what my actual screen dimensions were. A quick search led me down a rabbit hole of confusing forums and sketchy sites asking for permissions. So I made this. It runs in your browser, doesn’t track you, and gives you the answer in two seconds.

Whether you’re a designer tweaking a layout, a gamer checking your setup, or just curious, this tool cuts through the noise. It’s not fancy. It doesn’t need to be.

FAQ

Q: Why does my resolution look different than what the monitor box said?
A: Good question. Sometimes your OS scales things (like Windows’ 125% or 150% scaling), so the effective resolution feels smaller. This tool shows the actual pixel count your screen is using, not the advertised size. Also, some laptops run at lower resolutions to save battery—check your display settings if you’re unsure.

Q: Can this tool change my screen resolution?
A: Nope. It only reads what’s already set. To change it, you’re better off going into your system settings—Windows, macOS, or your Linux distro all have their own ways. This tool just tells you what you’re working with right now.
