Why Size Is Important
Size is not just a number, it directly affects the functionality and aesthetics of the space. Reasonable size can make the space more spacious and bright, unreasonable size may lead to congestion and inconvenience.

Dimensional planning principles for home space
When planning your home space, there are several basic principles that can help you make better size choices. First, consider the actual size and functional requirements of the room. Second, leave enough walking space to ensure free movement. Finally, pay attention to the coordination between the furniture, to avoid the size of the disharmony.
Ideal size for living room furniture
The living room is the main place for family members to gather and receive guests, so the choice of furniture is particularly important. Generally speaking, the length of the sofa should be about 200cm and the depth should be about 90cm, so that it will not take up too much space and ensure a comfortable sitting feeling. The height of the coffee table should be flush with the sofa seat surface, and the width should not exceed the 2/3 of the sofa. The height of the TV cabinet is generally between 60-70cm, and the distance from the sofa must be at least 3 meters for viewing.

Reasonable layout of bedroom furniture
The bedroom is a space for rest and relaxation, and the choice of bed is particularly critical. The standard size for double beds is 180cm x 200cm, while single beds are 90cm x 200cm. The height of the bedside table should be flush with the bed surface for easy access. The depth of the wardrobe is usually about 60cm, and the height of the clothes rail from the ground should not be less than 190cm to adapt to clothes of different lengths.
Best Size Selection for Kitchen Supplies
The height of the kitchen console is generally between 85-90cm, which can reduce the fatigue of bending over and is easy to operate. The width of the door panel of the cabinet should not exceed 60cm to prevent collision when switching. The depth of the drawer is generally 15-20cm, which is convenient for storing kitchenware. The height and width of the refrigerator should be selected according to the specific situation of the kitchen, but the standard size is 175cm x 70cm.
Small design for bathroom accessories
The bathroom space is relatively small, so it is very important to choose small and compact accessories. The height of the wash basin is generally between 80-85cm and the width is not more than 60cm. The length of the bathtub is usually between 150-170cm and the depth is 50-70cm. The size of the shower room needs to be at least 90cm x 90cm to ensure the comfort of use.
Scientific size of desk and chair
The height of the desk is generally between 72-76cm, the width of the desktop is at least 120cm, and the depth is 60cm, so that computers and other office supplies can be placed. The height of the chair should be adjustable, the seat width should not be less than 45cm, and the depth should be 40-45cm. The height of the backrest should be between 45-50cm to support the waist.
Proper proportion of decorations and artworks
Decorations and artwork are small, but they can play a finishing touch in the space. The height of the picture is generally 10-15cm above the line of sight level, and the width should not exceed the 1/3 of the wall. The height and width of the ornaments should be coordinated with the proportion of the surrounding furniture to avoid visual imbalance caused by too large or too small.
Advantages and choices of multifunctional furniture
With the limited living space, multi-functional furniture is more and more popular. For example, beds with storage functions, foldable dining tables, sofas with bookshelves, etc., these furniture not only save space, but also meet a variety of needs. When choosing, pay attention to the practicality of the function and the coordination with the overall decoration style.
Safety and comfort dimensions for children's rooms
The furniture in the children's room should pay attention to safety and comfort. The height of the bed should not be too high, it is best to have a guardrail to prevent the child from rolling down. The height of the study table should be between 60-70cm, and the height of the chair should be adjustable to adapt to the height of the child. The edges of toy boxes and bookshelves should be rounded to avoid damage caused by sharp edges and corners.
Dimensional considerations for outdoor furniture
Outdoor furniture must not only consider beauty, but also weather resistance and comfort. The height and width of the table and chair should be similar to the indoor furniture to maintain consistency. The height of the sunshade should be between 200-250cm and the diameter should not be less than 200cm to provide sufficient shading area. The length of the recliner should be between 180-200cm and the width 70-80cm to ensure the comfort of lying down.
Dimensional Measurement Tools and Methods
Accurate dimensional measurement is the basis for choosing the right furniture. Commonly used surveyors have tape measures, laser rangefinders and rulers. When measuring, make sure that the tool is close to the wall or the ground to avoid errors. Each dimension is recorded with a detailed location for subsequent reference.
