Knowing how to calculate the appropriate dimensions and standard sizes of beds will help make your resting space more spacious, suitable for various users, and moreover, align with feng shui principles to bring prosperity and good luck to the homeowner.
Below, Ru9 provides detailed and comprehensive advice on how to calculate the area and dimensions of beds suitable for different users and room sizes.
1. Standard Single Bed Dimensions
As the name suggests, a single bed is suitable for a single adult, children, or those with pets in a room smaller than 20m2. A single bed will help expand living space and make your room tidier.
What are the standard single bed dimensions today?
Some single bed dimensions you can refer to:
| Bed Type | Dimensions | Suitable Users |
| Small Single | 76x188 | Newborns, children, adults under 160cm tall. |
| Single | 97x188 | Newborns, children, single adults under 165cm tall |
| Single Extra | 97x201 | Newborns, children, single adults |
| Single King | 105x201 | Newborns, children, single adults |
| Single King Extra | 120x201 | Newborns, children, single adults |
2. Standard Double Bed Dimensions
Double beds are generally more popular and widely used than single beds because they suit a wider range of users and purposes. A double bed can accommodate 2-3 adults, or 2 adults and 1 child, or 2 adults with pets.
Double beds also come in many sizes for you to choose from to fit your room and decoration ideas, ensuring they meet your needs.
Below is a table of standard double bed dimensions.
| Bed Type | Dimensions (cm) | Best Suited For |
| Small Double | 122x191 | Newborns, children, single adults |
| Double | 137x191 | Children, single adults |

3. Bed Dimensions According to Feng Shui
Not only suitable for the room and a place for daily rest, according to ancient beliefs, the bed is also an important item that brings health, luck, and prosperity to the homeowner.
In reality, when buying a bed, many families often instinctively choose available models, making relative choices based on room area and their perception of arrangement and decor, without thoroughly researching the purpose of use, target users, and feng shui compatibility.
According to architects and feng shui masters, they use a Lu Ban ruler to measure the dimensions of the bed, as well as many other household items such as house height, windows, specific areas, etc.
The Lu Ban ruler has a specific length, with marked divisions and black and red lines. Currently, the most commonly used types of Lu Ban rulers are 52.2cm, 42.9cm, and 38.8cm, used for measuring water flow, kitchen and step construction, and household furniture like shelves, cabinets, beds, etc.
Refer to standard bed dimensions according to the Lu Ban ruler.
Among these, the 42.9cm Lu Ban ruler is widely used for measuring bed dimensions. When measuring a feng shui bed using the Lu Ban ruler, attention should be paid to the overall length, width, and height of the bed; for a round bed, measure the diameter.
Specifically, the 42.9cm Lu Ban ruler has an exact length of 429mm, divided into 8 major sections: Tài (Prosperity), Bệnh (Illness), Ly (Separation), Nghĩa (Righteousness), Quan (Authority), Nạn (Disaster), Hại (Harm), Mạng (Fate). Each major section has a length of 53.625mm and is further divided into 4 smaller sections. The length of each small section is 13.4mm. Auspicious sections are marked in red, inauspicious sections in black. When measuring, ensure that the bed's dimensions align with the red sections to bring good fortune to the homeowner.
There are 4 auspicious sections:
- Tài (Prosperity): From 1cm to 5cm, From 42.9cm to 48.3cm
- Nghĩa (Righteousness): From 16cm to 21.5cm
- Quan (Authority): From 21.5cm to 26.8cm
- Bản (Origin): From 37.5cm to 42.9cm
4. Mattress Sizes Compatible with Different Bed Types
It can be understood that mattresses and beds are two complementary items. Their lengths are based on each other's standard measurements. Mattress sizes also vary depending on the country.
According to statistical data, here is a table of mattress sizes compatible with standard bed types in Vietnam:
| Size | Mattress Type |
| 100x190 | Single type used for bunk beds, single beds, portable sleeping spaces |
| 120x200 | Single type used for bunk beds, single beds, sofa beds |
| 120x190 | Single bed type |
| 150x190 | Small double bed mattress type |
| 160x195 | Queen size mattress type |
| 160x200 | Large Queen size mattress type |
| 180x200 | Common King size double bed mattress type |
| 200x220 | Super King size, commonly used in hotels |
5. Buying Reliable, High-Quality Mattresses that Fit Bed Sizes
Which mattress should you choose for single or double beds?
For those using single beds, single mattresses are manufactured to fit a wide range of bed sizes. These single mattress models can also be used for long sofas, daybeds, bunk beds, shared bedrooms, or small guest rooms.
For small double beds or large single beds for those looking to save costs or with limited space, XS Single or Single mattress models can provide a luxurious feel similar to larger mattresses without incurring high costs or occupying much space.
If you notice, two XS Single mattresses can be combined to form one Square King mattress. Buying two single mattresses that can be placed side-by-side essentially still provides separate mattresses, allowing the sleeper to sit up or lie down without disturbing their partner.
Double mattresses from full size upwards are more suitable for those who prefer ample space when sleeping alone, lounging on the bed all day, or for couples, with or without children or pets.
Full or double-sized mattresses can be a challenging choice for couples sharing a bed with children or pets. Refer to the mattress sizes at Ru9.vn to choose the right mattress for you.
