How to calculate the square footage of furniture
When purchasing furniture, many people will pay attention to the size and floor space of the furniture. Especially for small households, it is necessary to accurately calculate the square footage of the furniture. This article will introduce in detail the calculation method of furniture square footage, and attach a structured data table to help you quickly master relevant knowledge.
1. Calculation method of furniture square

The square meter of furniture usually refers to the floor area of the furniture, that is, the projected area of the furniture on the plane. The calculation method is as follows:
| furniture type | Calculation formula | Example |
|---|---|---|
| Square furniture (such as dining tables, desks) | length × width | 1.5 meters × 0.8 meters = 1.2 square meters |
| Round furniture (such as round tables) | π×radius² | 3.14 × (0.6 meters)² ≈ 1.13 square meters |
| Modular furniture (such as L-shaped sofa) | Add after piecewise calculation | 2 meters × 0.9 meters + 1.5 meters × 0.9 meters = 3.15 square meters |
2. Things to note when calculating square footage of furniture
1.Reserve event space: When calculating the square footage of furniture, you need to reserve at least 30 centimeters of extra space to avoid crowding.
2.Consider the direction of opening the door: For furniture such as wardrobes and cabinets, the space occupied by opening doors or pulling out drawers must be considered.
3.high impact: Although the square calculation only involves length and width, the height of the furniture will affect the overall visual effect and storage capacity.
3. Common furniture square reference data
| furniture name | Common dimensions (length × width) | Floor area (square meters) |
|---|---|---|
| single sofa | 0.8m × 0.9m | 0.72 |
| double bed | 1.5m × 2.0m | 3.0 |
| Dining table for four | 1.4m × 0.8m | 1.12 |
| Standard bookcase | 0.9m × 0.4m | 0.36 |
4. How to optimize the square meter utilization of furniture
1.Choose multifunctional furniture: Such as sofa bed, folding dining table, etc., which can reduce the fixed floor space.
2.Make use of vertical space: High cabinets or wall cabinets can increase storage without increasing floor space.
3.custom furniture: Customize furniture according to room size to achieve zero waste of space.
5. Recommended furniture square calculation tools
1.Online calculator: Many decoration websites provide free furniture area calculation tools.
2.Mobile APP: Apps such as "Decoration Calculator" support AR measurement and furniture placement simulation.
3.traditional method: After measuring with a tape measure, calculate manually according to the formula in this article.
Through the above methods and data, you can easily calculate the floor area of furniture and provide a scientific basis for home layout. Properly planning the square footage of furniture can not only improve space utilization, but also create a more comfortable living environment.
