How to calculate the projected area of furniture
In furniture purchasing and space planning, projected area is a very important concept. It is directly related to the placement of furniture and the utilization of space. This article will introduce in detail the calculation method of the projected area of furniture, and attach a structured data table to help you better understand and apply this concept.
1. What is the projected area of furniture?
The projected area of furniture refers to the floor space of the furniture on the horizontal plane, usually calculated as the product of length and width. It is the actual floor area occupied by the furniture in the space, excluding the height of the furniture. The calculation of the projected area is very important for furniture placement, space planning, and size checking before purchasing.
2. Calculation method of furniture projection area
The calculation method of furniture projection area is relatively simple, mainly divided into the following situations:
| furniture type | Calculation method | Example |
|---|---|---|
| Rectangular furniture (such as beds, sofas, tables) | Projected area = length × width | A bed of 1.5 meters by 2 meters with a projected area of 3 square meters |
| Round furniture (such as round tables, round rugs) | Projected area = π × radius² | A round table with a radius of 0.8 meters has a projected area of ≈2.01 square meters |
| Irregular shaped furniture | Projected area ≈ maximum length × maximum width | An L-shaped sofa, with a maximum length of 2 meters, a maximum width of 1.5 meters, and a projected area of ≈3 square meters |
3. Practical application of furniture projection area
1.Space planning:Before purchasing furniture, calculating its projected area can help you determine whether it will fit the dimensions of your room. For example, a sofa with a projected area of 4 square meters may require a living room of at least 10 square meters to be placed comfortably.
2.Furniture matching:By calculating the projected area of different furniture, furniture can be matched appropriately to avoid space congestion or waste. For example, the projected area of the bed in a bedroom usually accounts for 30%-40% of the entire room area.
3.Purchasing decision:Knowing the projected area of your furniture can help you avoid buying furniture that is too large or too small. For example, the projected area of the dining table in a restaurant should match the restaurant space. Usually, the projected area of the dining table should not exceed 25% of the restaurant area.
4. Reference of projection area of common furniture
| furniture name | Common dimensions (meters) | Projected area (square meters) |
|---|---|---|
| single bed | 0.9×1.9 | 1.71 |
| double bed | 1.5×2.0 | 3.0 |
| three seater sofa | 2.1×0.9 | 1.89 |
| Dining table for four | 1.4×0.8 | 1.12 |
| desk | 1.2×0.6 | 0.72 |
5. Things to note when calculating the projected area of furniture
1.Contains all highlights:When calculating the projected area, all protruding parts of the furniture, such as sofa armrests, headboards, etc., should be included. These parts also take up space when physically placed.
2.Consider using space:In addition to the projected area of the furniture itself, you should also consider the activity space required when using it. For example, a chair requires an additional 0.5 meters of space when it is pulled out.
3.Measure actual size:It is best to actually measure the dimensions of the furniture before purchasing it, as the dimensions on the product specification sheet may differ from the actual dimensions.
4.Consider door opening space:For cabinet furniture, extra space needed to open the door should be reserved, and this part should also be included in the total space requirements.
6. How to optimize the use of furniture projection area
1.Choose multifunctional furniture:Such as sofa beds, storage beds, etc. can reduce the total projected area.
2.Make use of vertical space:Choosing tall and narrow storage cabinets instead of wide and short ones can reduce the projected area while maintaining storage capacity.
3.Reasonable layout:Placing furniture against the wall and leaving a central activity area can improve space utilization.
4.Choose transparent furniture:Furniture made of transparent materials such as glass coffee tables and acrylic chairs will visually reduce the feeling of crowding.
Through the above methods and data, I believe you have mastered the calculation and application skills of furniture projection area. Reasonable calculation and use of projected area can make your home space both beautiful and practical.
In real life, the calculation of the projected area of furniture is the basic work of home planning. I hope the structured data and practical advice provided in this article will help you create a more comfortable and reasonable living environment.
