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.

WWMS PRO TIP

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. A width of 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?

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.

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.

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.

Step 4: Think About Table Width

Length gets all the attention, but width matters just as much for how the table feels day-to-day. Standard dining tables range from 36" to 48" wide. Here's what that feels like in practice:

36" wide: Room for two place settings across from each other plus a centerpiece — but tight. Conversation is easy; serving dishes are a stretch.
40"–42" wide: The sweet spot for most households. Comfortable place settings, room for serving pieces in the center, not so wide that conversation feels distant.
44"–48" wide: More formal and grand. Great for entertaining. May feel like too much space for a family of two or three on an everyday basis.

For live edge slabs, this is where things get interesting — and where the natural material leads the design rather than the other way around.

Step 5: Understand Your Material Options

One of the most rewarding parts of a custom table is choosing the material. Here's a plain-language breakdown of the options and the terms you'll encounter.

Slab vs. Lumber Construction

Slab (Live Edge): A slab is a thick cross-section cut from a log — essentially a slice of the whole tree. A live edge slab keeps the natural outer edge of the tree intact, giving the table its organic, irregular profile. No two live edge slabs are alike. Each one reflects the tree's growth history: its curves, its grain, any character marks left by the environment.

Slab (Straight Edge): The same thick, single-piece construction as a live edge, but the natural edge is trimmed to a straight, clean line. Great for clients who want the character of a solid slab with a more tailored look.

Lumber Construction: Standard dimensional lumber is milled to consistent thickness and then glued or joined to create the tabletop. This approach offers more flexibility in size and is often more cost-effective for larger tops. It can be just as beautiful — especially when the grain is carefully matched across boards.

Book Match and Yin/Yang

Book Match: When a log is sliced and the two adjacent pieces are opened like a book, they create a near-mirror image. Book matching is commonly used to achieve wider tabletops than a single slab can provide, or simply for the dramatic symmetry of the grain pattern. Because trees don't always grow wide enough for a single-slab table, book matching is often the best path to a wide, natural-looking top.

Yin/Yang (Flip Match): A variation where one slab is flipped rather than mirrored — creating a complementary shape rather than a mirror image. The two live edges often form an oval or lens shape in the center. This approach can be particularly striking with figured grain.

Live Edge Orientation: Which Way Does the Wide End Go?

Live edge slabs taper — they're not the same width from end to end. This means you have a choice about orientation: wide end toward the head of the table, or toward the foot.

We generally recommend placing the wide end up (toward the primary seating end or the most-viewed side of the table).
Here's why:

More surface area where it matters most for seating.
A long, sloping edge on the narrow end is less likely to cause things to roll or slide off.
Visually, it tends to feel more grounded and intentional.

That said, this is ultimately an aesthetic choice — and we'll discuss options with you. A simple line drawing or photo mockup can help before anything is committed.

Resin and Epoxy Fills

You may have seen the dramatic "River Table" trend — large pours of colored epoxy running through a slab. We generally steer away from large resin pours; we find they tend to age visibly and can distract from the wood itself.

Where we do use resin: filling small natural cracks and voids in the slab. This isn't just cosmetic. Filled voids:

Stabilize the slab and prevent the crack from expanding over time.
Eliminate crumb catchers — places where food and debris collect in crevices.
Can be done with a clear or tinted resin to blend or contrast with the wood, depending on your preference.

Wood Grain and Sawn Types

If you're working with a lumber-based top, how the boards are cut from the log affects both aesthetics and performance. From your design consultation, here's a quick reference:

Plain Sawn (Flat Sawn)

The most common cut. Produces characteristic cathedral grain patterns. Cost-effective and widely available, though more prone to movement with seasonal humidity changes.

Rift Sawn

Cut at roughly 45° to the growth rings. Produces a linear, consistent grain with no ray fleck. Very stable. More waste in production, so it costs more.

Quarter Sawn

Cut at 60–90° to the growth rings. Produces tight, straight grain with ray fleck (those shimmery, ribbon-like streaks in oak and other species). Very stable. High cost due to waste.

WWMS PRO TIP

For a dining table that will see daily use and seasonal humidity changes (especially relevant in Colorado's dry climate), quarter sawn or rift sawn lumber offers more stability over time. We'll discuss this during your consultation.

Quick Glossary of Terms You'll Encounter

You don't need to be an expert before you call us — but knowing these terms helps conversations go faster and ensures you get exactly what you have in mind.

Annual Ring (Growth Ring)

The visible ring in a cross-section of a tree trunk representing one year of growth. Tighter rings generally indicate slower growth and denser, more stable wood.

Burl

An irregular, rounded growth on a tree trunk or root. Burls are highly prized for their dramatic, swirling grain patterns. Often used for accent pieces, inlays, and decorative tabletops.

Check

A lengthwise crack or split in the wood, usually caused by uneven drying. Small checks are a natural characteristic of solid wood and can be left as-is or filled with resin.

Figure / Figured Grain

An unusual or particularly decorative grain pattern — such as curly, quilted, or bird's eye figure. Highly figured wood is prized and typically more expensive.

Heartwood

The dense, darker-colored wood at the center of the tree. Harder and more rot-resistant than sapwood. Typically the most prized section of the log.

Kiln Dried

Wood that has been dried in a controlled kiln to a target moisture content. Properly kiln-dried lumber is more dimensionally stable and less prone to warping than air-dried wood. All slabs at WWMS are kiln dried in-house.

Live Edge

The natural outer edge of a slab, retaining the contour of the original tree. May include bark, sapwood, and natural undulation.

Sapwood

The lighter-colored wood near the outer edge of a log, between the bark and the heartwood. Sapwood is softer and more variable in color. Whether to include or remove it is a design choice.

Slab

A thick, wide piece cut from a log, retaining its natural width. Distinguished from standard lumber by its size and the fact that it typically comes from one continuous cross-section of the tree.

Warp

Any deviation from a flat surface: bow, cup, twist, or crook. Proper kiln drying and joinery technique minimize warp in finished pieces.
