Do you know how to calculate the depth of a room?
In architectural design and decoration, bay and depth are two very important concepts. Knowing how to calculate depth will not only help you plan your space properly, but also improve your living comfort. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the relationship between opening and depth, and provide structured data for reference.
1. Definition of bay and depth

Bay usually refers to the horizontal distance in a building, that is, the width of a room; depth refers to the longitudinal distance, that is, the length of a room. The proportional relationship between the two directly affects the lighting, ventilation and usage efficiency of the space.
| Terminology | definition | unit |
|---|---|---|
| bay | Lateral distance (width) of the room | Meters (m) |
| Go deeper | Vertical distance (length) of the room | Meters (m) |
2. How to calculate depth
Depth calculations are usually based on the functional requirements of bays and rooms. The following are common calculation methods:
| room type | Recommended bay to depth ratio | Example calculation (bay 4m) |
|---|---|---|
| living room | 1:1.5 to 1:2 | Depth=6m-8m |
| bedroom | 1:1.2 to 1:1.5 | Depth=4.8m-6m |
| kitchen | 1:1 to 1:1.2 | Depth=4m-4.8m |
3. Analysis of hot topics on the entire network
In the past 10 days, discussions on openings and depths have mainly focused on the following hot spots:
