Wallpaper size tools

Four small calculators for getting a wallpaper to fit: what your screen is, what shape it has, and what happens to an image of another shape.

• Screen resolution checkerWhat your browser reports about your screen, and the resolution it suggests.
• Aspect ratio calculatorReduce any width and height to its ratio, or resize while keeping the shape.
• Multi-monitor wallpaper sizeThe canvas size for one wallpaper across two to four screens in a row.
• Wallpaper crop & fit calculatorHow much of an image a screen of another shape crops, or how big the bars are.

Everything is calculated in your browser. Nothing you type is sent or saved.
