Table dimensions are important when planning your dining room’s layout and when purchasing linens, tablecloths, and chairs. No host wants to welcome guests to their home for a holiday dinner and realize there isn’t enough room for everyone.

When this happens, the folding card table usually gets dragged out, and the kids get seated at the end, feeling, at times, left out. This article will help you avoid cramped furniture, narrow walkways, and tables that are too small for your dinner party by outlining standard dining table dimensions. [toc]

Standard Dining Table Dimensions

Standard Dining Room SizeDining room tables are typically designed with one of three shapes: square, rectangle, or circle. Some tabletops are designed using real wood in its natural state with naturally uneven edges. However, standard measurements still apply as the overall size and shape determine how many people can fit comfortably at the table.

Rectangle Sizes

Below are the standard sizes per number of people who can be seated at each size and shape table. Remember, if you purchase a tabletop with leaves, check where the leaves are stored. It’s more convenient to store them underneath than keep the leaves in a closet.

While rectangular dining room tables offer many configurations based on the number of people you want to seat, choosing one that’s at least 36″ but not more than 40″ wide is recommended.

This allows enough room for place settings and leaves enough room for passing food platters. If you plan on purchasing a sideboard or food buffet as part of your dining room set, a 30-inch wide tabletop will also work well.

For the table’s length, figure out the most people you’d like to seat at the same time and choose a length to fit everyone. Remember that the basic rule is 24″ of space per person per side.

Square Sizes

Round tables are similar to square shapes when fitting in a small space. The diameter, or the length from one edge to the other crossing the center, is the size used to measure round tables.

How Do You Determine the Size of a Table?

First, consider the width and length of your dining room and where windows and other pieces of furniture will be placed. It helps to draw a square on a piece of paper representing the dining room size, using a quarter-inch to represent each foot along the four walls.

Allow for indents and irregular built-ins by drawing these on the lines. Erase the line for the length of the door or opening along the wall it’s located.

Measure the width and depth of any furniture you will be adding in addition to the dining room tabletop. Draw these up against the lines representing each wall. (Tip: if you cut out the pieces of furniture from another sheet of paper, you can easily move them around to rearrange placement.)

Once complete, draw another square in the middle of the room, leaving clearance around the table’s sides for people to pass through.

The best distance is 48″ from the table’s edge to the nearest wall or piece of furniture, with A minimum clearance of 30″. The square needs to be drawn at the distance you prefer for clearance. When you’re done, measure the length and width of the square. This is the largest size allowed for the furniture piece.

Dining Room Layout

Manufacturers design and build dining room furniture with a set of standard sizes as their guide. This allows for chairs and benches to be made to fit each size and shape.

A dining room requires more space to move around in than a kitchen or bedroom. Plan a layout around the dining room furniture you need using the instructions above. You may need to factor in extra furniture first.

Lighting is another important consideration when laying out your dining room design. We have more details about dining room chandelier sizes here or read more about the types of dining room lighting.

A dining room may be any size or shape but typically equals two hundred square feet. This may be laid out as 10 feet by 20 feet. Larger dining rooms may be 14 feet by 18 feet or more.

Table Seating Arrangements

Always plan your dining room layout and table’s size around the largest capacity of people you plan on having around the tabletop. Sometimes, a chair can be pulled up to join, or guests may be seated on a veranda or patio.

Avoid overly large centerpieces, especially on round tables that can block other guests’ views. Remember, if you purchase a tabletop with one or more leaves, the full length and width have to fit in your dining room.

For the traditional formal seating arrangement, hosts sit at the head and foot, with honored guests directly to the right side of the host. With a more informal family style, all family members sit together, with kids in the middle and parents on opposite sides.
