The ideal distance between chairs in a dining table can vary depending on the size and shape of the table and the chairs, as well as the number of people who will be seated at the table. In general, there should be enough space for each person to comfortably sit in their chair and move around the table without feeling crowded.
As a general rule of thumb, chairs should be spaced about 24 to 30 inches apart from one another around a dining table. This allows for enough space for each person to comfortably sit and move around the table, as well as allowing for adequate space for serving dishes and platters. However, when entertaining more guests, you can leave as a little as 6 inches of space between chairs.
It's also important to consider the size and shape of the dining table and chairs when determining the ideal distance between them. For example, round or oval tables may require more space between chairs to allow for comfortable movement around the table, while rectangular or square tables may be able to accommodate chairs placed closer together.
Ultimately, the ideal distance between chairs in a dining table will depend on the specific needs and preferences of the people using the table. Consider the size and shape of the table and chairs, as well as the number of people who will be seated at the table, to determine the ideal spacing for your dining space.
