If you are looking for a table to suit an urban-industrial decor theme, don’t go all-out with a (heavy) metal table but consider a (lighter) wood table with some metal design features.
To visualize how a bigger piece of furniture will look, take the time to block out the length and width on the floor, and also the height of the table. I usually stand on my tape corners with a tape measure, then try to fill in that space with furniture of a similar size, and take a step back to see how it’ll feel. It also helps to have a friend stand there with the tape measure while you have a look.
Consider a designer pack-and-go dining table. Plywood is lightweight and durable, and a plywood table can be flat-packed and assembled as needed at home. Your dining table then can be packed up and moved as necessary. Plus it works well in a home with modern Nordic or contemporary Asian style.
Square and rectangular tables are the most common, so you’ll find the greater number of choices there with styles, sizes and extendable options. But a round or oval table can give you a little more space to move around since it cuts off the corners but still has a good surface area.
