- Doors and windows are simple rectangular shapes and align with the walls cleanly.

## Use Cases for This Calculator

### Determine the Number of Rolls Needed

When planning a room makeover, accurately determining how many rolls of wallpaper you need is essential. You input the dimensions of your walls, and the calculator assesses the total area, factoring in the roll dimensions to provide an accurate estimate of rolls needed.

### Calculate Waste Factor

If you’re worried about mistakes or mismatched patterns, this calculator helps you account for waste. By inputting the complexity of your chosen wallpaper pattern, you’ll receive an adjusted number of rolls, ensuring you have enough for those missteps.

### Estimate Cost of Wallpaper

You can quickly gauge your budget for a wallpaper project by entering the price per roll and quantity required. This feature helps you avoid overspending and allows for informed decisions on materials without breaking the bank.

### Adjust for Ceiling Height

The calculator allows for adjustments based on ceiling height, which can significantly impact the total wallpaper needed. Input different heights to see how this affects your roll requirements, ensuring you plan accurately for your uniquely shaped rooms.
