How to calculate the required size?
If you decide to buy factory furniture, before going to the store it is better to calculate these sizes “for yourself”. First of all, decide how the table will be. If you acquire a new table, you need to decide on its choice, and then take up the other furniture items. There is some standard formula for calculating, which will be discussed below.
To begin with, measure your growth and the growth of other family members. It is necessary to calculate the average height of your household. It takes as a medium-ray of growth. For example, your growth is 178 cm, the average growth of the family is 167 cm. Next, we take relation: 178 * 75 (standard height) / 167 = 79.9 cm. It will be the perfect height of the kitchen table.
Now take away from the resulting digit from 40 to 45 cm (depending on the growth: the higher the person, the closer to 45 cm). In the example above, it turns out 79.9-43 = 36.9 cm. This is the optimal distance from the table to the seat. The backrest length choose at its discretion, but remember that the standard size is 90 cm.
Such a formula is also valid when choosing a bar objects, and office, but for children’s models it is better to repel from standard sizes or buy by “fitting”.
