How to Plan Your Custom Dining Table

A practical guide to sizing, materials, and everything your shop team needs to build it right.

A dining table is often the most-used piece of furniture in a home. It's where family gathers, homework happens, and guests linger long after dinner. Getting the size right — and understanding your material options — makes the difference between a table you love for decades and one that never quite works.

This guide walks you through everything you need to consider before commissioning a custom dining table: how to size it for your space and your household, what height works best for your chairs, and what material terms actually mean when you're browsing slabs and talking to your fabricator.

Go bigger. A generous table doesn't just fit your space — it defines it. Our clients consistently find that sizing up gives them the flexibility to entertain, gather, and grow into a piece they'll have for decades.

Step 1: Measure Your Space First

Before choosing a table size, know your room. The single most important clearance rule is this:

Allow a minimum of 36" between the table edge and any wall or obstruction.

This gives someone room to pull out their chair, sit down, and get up without bumping into the wall or sideboard behind them. 42"–48" is more comfortable if your space allows it, especially in high-traffic areas.

How to calculate your maximum table size:

Measure the room length and width.
Subtract 36" from each side (72" total from a pair of walls on one axis).
The result is your maximum table dimension in that direction.

Example: A 12 ft × 11 ft dining room (144" × 132") minus 72" on each axis leaves a maximum table size of roughly 72" × 60" — about a 6 ft × 5 ft table. That's a reasonable dining room. Go bigger in a more open floor plan.

Step 2: How Many People Do You Need to Seat?

The standard guideline is 24" of table width per person seated along the sides. This is a comfortable minimum — think of it as the width of a place setting with a little elbow room. For a more relaxed feel, 26"–28" per person is even better.

The key variable that most people overlook: do you want seating at the short ends of the table?

WWMS PRO TIP

If you entertain frequently, size your table for your dinner party guest count, not your everyday count. The extra space on a regular Tuesday is rarely a problem.

Note: "With ends" assumes one person per short end. This only works comfortably if the table is at least 36" wide and your end chairs don't conflict with side chairs at the corners.

Step 3: Choose the Right Height

Table height interacts directly with your chair choice — and with the heights of the people using the table. Most dining tables are built at a standard height, but counter-height and bar-height options exist for specific aesthetics or settings.

A note on household height differences

If the people using the table vary significantly in height — say, one partner is 5'4" and the other is 6'3" — there are a few options worth discussing:

A standard 29"–30" table works for most people with standard chairs.
Taller individuals may be more comfortable at a slightly higher table (30") with a chair that accommodates longer legs.
A footrest rail on the table base can make a real difference for shorter users at taller tables, giving them something to rest their feet on rather than dangling.

WWMS PRO TIP

If you're buying new chairs alongside your table, bring the chair dimensions (seat height, arm height) to your fabricator before finalizing table height. Arm chairs in particular need enough clearance to slide under the apron of the table.

Chair arms and table apron clearance

This is one of the most common oversights in dining table planning. If your chairs have arms, they need to clear the table apron — the structural frame that runs around the underside of the tabletop.

Standard apron drop is 3"–4" below the tabletop surface.
Measure the arm height of your chair from the floor, then compare to table height minus apron depth.
Most arm chairs need at least 7" of clearance between the seat and the underside of the apron to slide under comfortably.
