Finding the right dining table size is the single most important decision you'll make for your dining room. Get it right, and every meal flows—elbows clear, servers pass easily, and guests slide in without scooting the whole row.
Get it wrong? Even the most beautiful table feels cramped.
The challenge? Search intent is fractured. Some shoppers think in feet, others in centimeters. Some need a 6-seater dining table size in meters, while others search for dining table measurements in inches. You might be certain you want a rectangle, then fall in love with a round. This guide solves that. It is the 2026 Ultimate Dimension Reference, built from NKBA standards and real room data. We cover 4, 6, 8, and 10 seats, both rectangular and round, in inches, cm, feet, and meters.

Standard Size of Dining Table for 4 (Rectangular & Round)
Four-seater tables are the backbone of apartment living and breakfast nooks. You don't need a ballroom; you need efficiency.
What is the size of a standard dining table for 4?
Rectangle: 60" long x 36" wide (152 x 91 cm). This gives each diner the essential 24" of elbow width.
Round: What size round table seats 4 comfortably? A diameter of 36" to 42". At 36", it’s cozy but perfectly functional for four placemats. At 42", you gain center space for a pitcher or vase.
Space Tip: You only need about 10' x 10' of floor space to float a 42" round table with 36" of walking clearance.

Standard Size of Dining Table for 6
Six-seaters are the most searched category because they represent the "average host"—family dinners plus the occasional friend pair. This is also where unit confusion peaks.
What size table is a 6 seater? It depends entirely on the shape and how often you use the ends.
Seater Rectangular Dimensions
What is the normal size of a 6 seater dining table?
Minimum: 72" L x 36" W (183 x 91 cm). This fits three people per side tightly.
Comfort Standard: 78"–84" L x 38"–40" W (198–213 x 97–102 cm). The extra length prevents "center-bowl reach anxiety," and the width allows for shared platters.
HERNEST Pick for 6: The Thorsten Oval Dining Table
What size round table seats 6 comfortably?
This is the #1 geo-fenced question. Here is the absolute truth:
What is the diameter of a 6-seater round dining table?
Minimum: 48" diameter. You can fit six, but chairs will overlap. Best for breakfast, not roasts.
Sweet Spot: 54" diameter. This is the magic number. Six chairs fit with distinct zones.
Luxury: 60" diameter. This actually bleeds into 6-8 seat territory.
Can you fit 6 chairs around a 42-inch round table?
No. 42" is strictly a 4-seater (max 5 in a pinch). Do not attempt six; chair arms will collide.
Six-seater dining table size in cm:
Rectangular Comfort: 213 cm L x 100 cm W
Round Diameter: 137 cm (54") – 152 cm (60")
6 seater Dining Table size in meters:
Rectangular: 2.1m – 2.4m L x 1.0m W
Round: 1.37m – 1.52m Diameter
Standard Size of Dining Table for 8
While POVISON and Castlery cover this, we add the "Large Home" layer. An 8-seater isn't just a bigger 6-seater; it changes how the room breathes.
Standard size of dining table for 8:
Rectangle: 84"–96" L x 38"–44" W (213–244 x 97–112 cm).
Round: 60"–72" diameter. A 60" round table seats 6–8; for true 8-person comfort (without overlap), step up to 72".
Dining table standard size in feet:
8-Seat Rectangle: 7–8 ft Long x 3.2–3.6 ft Wide
8-Seat Round: 5–6 ft Diameter

Standard Size of Dining Table for 10 & Large Homes
Ten seats move you into "entertainer" territory. Proportions shift.
Standard size of dining table for 10:
Rectangle: 96"–110" L x 40"–46" W (244–280 x 102–117 cm).
Round: 72"–84" diameter. What size round table seats 8-10? 72" is the pivot; it seats 8 richly, 9-10 tightly. 84" guarantees 10.
Dining table standard size in feet: 8–9 ft long is the norm; 10 ft tables usually require custom spacing.
Pro Styling Tip for Large Homes:
With tables over 100", the visual weight of the base matters. You want anchor points, not a solid block. The Silas base design (multiple concentric arcs) scales beautifully at this size, preventing the table from looking like a "dormitory refectory" slab.

Table Measurements Length and Width—The "Comfort Math"
If you forget every number, remember this rule:
Table length needed = (Number of diners x 24") + (End clearance if using ends).
6 seats: Usually 2 per side (48") + 2 ends (24" total) = 72" minimum. This is why 6 seater dining table size in meters often rounds to 1.8m–2.1m.
Table width:
36": Works. No center row space.
39"-40": The Goldilocks zone. You can fit plates, glasses and a shared bowl down the middle.
42"+: Luxury zone; requires deeper reach to pass salt.
FAQ – People Also Ask
1. What is the size of a standard dining table?
A standard dining table is 28–30 inches (71–76 cm) high. For 4 people, a rectangle is usually 60" x 36"; a round is 42". For 6 people, the standard rectangle is 72–80" x 36–40".
2. What is the average size of a round dining table?
The average round dining table diameter is 48" to 60". 48" is the most common for 4-5 people; 54" is the average for 6 people.
3. What size round table seats 8-10?
A 72" diameter round table comfortably seats 8, and can fit 9-10 in a casual setting. For dedicated 10-seat round dining, choose 78"–84".
4. Can you fit 6 chairs around a 42-inch round table?
No. 42" is designed for 4 chairs. While you can physically place 6 chairs, the elbow overlap makes full-course dining uncomfortable.
5. What is the normal size of a 6-seater dining table in cm?
In Europe and Asia (CM-dominant search), the normal size is 200-220 cm length x 90-100 cm width for rectangles, or a 137 cm (54") diameter for rounds.
6. Dining table standard size in feet for an 8-seater?
Length: 7–8 feet. Width: 3.2–3.5 feet.
7. How much space do I need for a Round Dining Table Set for 6-8?
For a 54–60" round table, you need a room that is at least 12' x 12'. Add 3' of clearance on all sides. If the room is rectangular, an oval (like the Thorsten) fits better than a true circle.
8. What is the best material for a standard-size dining table?
For standard sizes (4-6 seater), sintered stone (like the Arcen or Silas) offers zero-maintenance heat/scratch resistance. For solid-wood warmth, Thorsten's walnut offers durability and refinishability.
Final Thought:
The "best" dining table size isn't just the one that fits your chairs—it's the one that fits your life. Use the charts above to find your baseline, then adjust based on how you actually eat: elbow-out relaxer, or formal placement? Your table should serve the meal, not the other way around.
