What are the sizes of various tables? Can someone tell me more about them? The table is one of the necessary furniture for children. There are many sizes of tables, mainly the following sizes: square tables

760mm×760mm square table and 1070mm×760mm long square table are commonly used table sizes. If the chair can reach into the bottom of the table, even in a small corner, you can put a table for six. When eating, just pull the table out a little. The width of the dining table of 760mm is the standard size, at least not less than 700mm, otherwise the table will touch the other's feet because it is too narrow when sitting. The feet of the dining table should shrink in the middle. It would be inconvenient to arrange four feet at four corners. Generally, the height of the table is 7 10mm, the height of the chair is 4 15 mm, and the desktop is low, so you can clearly see the food on the table when eating.

round table conference

If the furniture in the living room and dining room is square or rectangular, the diameter of the round table can be increased from150 mm. In ordinary small and medium-sized units, if the dining table with the diameter of 1200mm is used, it will often appear too large. You can customize a round table with a diameter of 1 140mm, which can also seat 8-9 people, but it looks more spacious. If you use a dining table with a diameter of more than 900mm, you can sit a lot of people, but it is not advisable to put too many fixed chairs. For example, a dining table with a diameter of 1200mm and eight chairs is very crowded. Can hold 4-6 chairs. Use folding chairs when there are many people, which can be stored in the storage room.

Open and close tables

The opening and closing table, also called the extended dining table, can be changed from a 900mm square table or round table with a diameter of 1050mm to a long table or oval table with a diameter of 1350- 1700mm (various sizes), which is very suitable for small and medium-sized houses and ordinary guests. This kind of dining table has been popular since15th century and has a history of 500 years. This is a very popular dining table. However, attention should be paid to its mechanical structure, which should be smooth and smooth when opening and closing, and easy to align and close when closing. With a round dining table, you can get better space adjustment. Another advantage of dining at a round table is that the number of people sitting is more tolerant. As long as the chair is pulled away from the desktop, more people can sit, and there is no disadvantage that it is inconvenient to sit in the corner when the square table is used.

The size of the table is so much.

There are also ceramics, purple sand, various stones and so on. Personally, I think the best and most practical one is Muzhu. In terms of color, it is better to choose tea trays that are in harmony with the colors of furniture and tea sets, such as China red tea sets and blue and white tea sets, and it is best to match antique tea trays. The same is true in style, such as glass tea sets, which are more modern and more suitable for bamboo dishes; Classical purple sand can be purple sand or mixed stone or dark high-grade wooden plate. Style coordination system. From the style point of view, there is a drawer type, which can be connected with a catheter to lead out wastewater; There is a water storage type, which can be a drawer or a box under the cover to store water. In short, the more expensive the tea tray, the better. It needs to be coordinated with people, environment and electrical appliances, and coordination and unification is the best choice. A good tea basin is not only an instrument for making and drinking tea, but also a reflection of the owner's taste. I wish you a favorite tea basin.
