In the past 10 days, the calculation method of the unfolded area of tatami has become a hot topic in the field of decoration and home furnishing. Many users have asked questions on social media and Q&A platforms, hoping to know how to accurately calculate the area of a tatami so that they can plan their space and budget appropriately. This article will combine hot topics on the Internet to provide you with a detailed analysis of the calculation method of the tatami unfolded area, and provide structured data for reference.
1. Basic concept of tatami expansion area
Tatami is a traditional Japanese flooring material, usually made of straw mats or composite boards. Its unfolded area refers to the actual area occupied by the tatami when it is laid flat, not the size when it is folded or rolled up. When calculating the expanded area, the size and number of tatami mats and the layout of the room need to be considered.
2. Calculation method of tatami unfolded area
1.Standard size calculation method: The common size of tatami is 90cm × 180cm (i.e. "one post"), but there are also other specifications such as 95cm × 190cm or customized sizes. To calculate, simply multiply the area of a single tatami by the quantity.
| Tatami size (cm) | Single block area (㎡) | quantity | Total expanded area (㎡) |
|---|---|---|---|
| 90×180 | 1.62 | 5 | 8.1 |
| 95×190 | 1.805 | 4 | 7.22 |
| Customized 100×200 | 2.0 | 3 | 6.0 |
2.Room area deduction method: If the room has an irregular shape, the total area of the room can be calculated first, and then the area occupied by furniture or obstacles can be deducted. For example:
| Total room area (㎡) | Deduction area (㎡) | Actual unfolded area of tatami (㎡) |
|---|---|---|
| 12 | 2 (wardrobe) | 10 |
| 15 | 3 (pillars) | 12 |
3.actual measurement method: For non-standard house types, it is recommended to use a tape measure to measure the length and width, and then multiply them to get the area. For example: length 3.5 meters × width 2.8 meters = 9.8㎡.
3. Answers to popular questions on the entire network
1.Are the gaps between tatami mats included in the area?
Answer: Usually it is not included, but if the gap exceeds 1cm, it is recommended to reserve 5% for loss.

5. Summary
Calculating the expanded area of tatami requires a combination of size, quantity and room layout. The standard size method is suitable for regular spaces, the deduction method is suitable for rooms with obstacles, and the actual measurement method is the first choice for complex house types.
