Quick answer
A round wooden tray 40cm across is about 15.7 inches in diameter, a common size for coffee tables, ottomans and serving drinks for four to six. Usable space depends on the rim: with a 1.5 cm wall, the flat inner circle is 37 cm, about 1,075 square centimeters (167 square inches). Always confirm the diameter in the specifications: we found a listing titled "40cm" whose specifications gave 24 cm.
40cm round wooden tray: sizes compared
| Outside diameter | In inches | Inner diameter with 1.5 cm wall | Inner area |
|---|---|---|---|
| 40 cm | about 15.7 in | 37 cm | about 1,075 sq cm (167 sq in) |
| 45 cm | about 17.7 in | 42 cm | about 1,385 sq cm (215 sq in) |
| 50 cm | about 19.7 in | 47 cm | about 1,735 sq cm (269 sq in) |
| 60 cm | about 23.6 in | 57 cm | about 2,552 sq cm (396 sq in) |
Each step up in diameter adds more area than you might expect: a 50 cm tray has roughly 60% more usable area than a 40 cm one with the same wall. For drinks on a coffee table, 40 cm is usually plenty; for a centerpiece with candles and greenery, 50 cm gives room to group things.

Title versus specifications
Sizes in titles are not always the size of the product. In our research, a listing titled "40cm Platter Tray" gave a diameter of 24 cm (9.45 inches) in its specifications, presumably because the seller offers several sizes. Another listing at 40 cm was a solid wood round table top, not a tray. Read the specifications and the selected size option before buying.
Care
- Follow the tray's own care: decor trays may say dry cloth only.
- Hand wash serving trays quickly; never soak.
- Dry on edge.
- Store large round trays on edge to save space.
Before you buy: what to confirm in the listing
For a 40 cm round tray, confirm the diameter in the specifications and the selected size option, and calculate the inner diameter from the wall thickness. In our research, one listing titled 40cm gave 24 cm in its specifications. Check whether it is a decor tray (often lacquered, wipe with a dry cloth) or a serving tray with a stated food use, and whether it has handles.
Check the material and weight too. Solid wood trays of this size can be heavy; bamboo and MDF are lighter.
Our take
A 40 cm round tray is one of the most flexible sizes you can buy: right for small ottomans, coffee tables and drinks for a group. Confirm the real diameter, calculate the inner space, and step up to 50 cm only when you need room for a larger centerpiece.
What affects the price
Round trays around 40 cm vary in price with material and finish. Decor trays with painted or washed finishes are often inexpensive; solid wood serving trays with raised edges cost more, and bamboo sits in between. Handles and thicker walls add cost. Because a 40 cm tray is a versatile size, it is worth paying for solid construction if you will use it daily.
Round trays by room
A 40 cm round tray is one of the most versatile sizes because it fits so many surfaces. In a living room it suits most round and small square ottomans, with space left around it. On a dining table it makes a modest centerpiece for a table of four. In a kitchen it gathers oils and spices next to the stove, though it should stay away from the hottest spots.
In a bedroom, a 40 cm tray on a dresser holds perfume bottles, a jewelry dish and a small plant. In a bathroom, it can hold soaps and towels, provided its finish copes with humidity; lacquered decor trays usually manage better than raw wood. On a balcony or patio table it can carry drinks out and back, but should not be left outside.
When a 40 cm tray feels too small, it is usually because the furniture is large or you want to group many objects. Step up to 50 cm for big ottomans and centerpieces, or use two 40 cm trays side by side, which can look more deliberate than one oversized tray and are easier to store.
Materials for round trays around 40 cm
At around 40 cm, round trays are made in solid wood, bamboo, MDF with a decorative finish, and rattan or metal. Solid wood and bamboo are the usual choices for serving, with raised edges to keep glasses in place. Decor trays in this size often have beaded edges, washes or lacquers and are best for display. Rattan and metal trays are outside the scope of this site but are worth comparing if weight matters.
Weight differs a lot: a thick solid wood 40 cm tray can be heavy before anything is on it, while bamboo and MDF are lighter. If the tray will be carried often, check the listed weight and choose a lighter construction or one with handles.
Cleaning and storing a large round tray
Large round trays are awkward to wash in a kitchen sink, which is one reason wiping is the usual care. Wipe with a damp cloth and mild soap, rinse with a clean damp cloth and dry immediately. For storage, stand round trays on edge between other trays or behind a cupboard door, or hang them on the wall as decor between uses.
When to choose two trays instead
If a single round tray would need to be larger than about 50 cm, consider two smaller trays. They are easier to carry, store and arrange, and a pair can frame a centerpiece or split food and drinks on a large ottoman.
Getting the size right online
When shopping online for a 40 cm tray, read the specifications and the selected size option, compare the diameter in both inches and centimeters, and measure on arrival. Return promptly if the size does not match the listing.
Converting and comparing sizes
| Centimeters | Inches (approx.) | Common US listing size |
|---|---|---|
| 30 cm | 11.8 in | 12 inch |
| 35 cm | 13.8 in | 14 inch |
| 40 cm | 15.7 in | 16 inch |
| 45 cm | 17.7 in | 18 inch |
| 50 cm | 19.7 in | 20 inch |
| 60 cm | 23.6 in | 24 inch |
Because listings round, a "16 inch" tray and a 40 cm tray are close but not identical. Two or three millimeters rarely matter; a centimeter or two can, if the tray must fit a specific ottoman or recess.
Furniture fit for round trays
- Measure the furniture top: diameter for round ottomans, width for square ones.
- Decide on a visible margin around the tray (a few inches is common).
- Subtract twice the margin from the furniture size to get the tray diameter.
- Check the tray's height against anything above it, such as shelves.
- If handles stick out, make sure they do not hang over the edge.
Common mistakes
| Mistake | Result | Fix |
|---|---|---|
| Trusting the size in the title | Tray arrives smaller | Check specifications and the chosen size option |
| Ignoring a tall wall | Much less flat space | Calculate the inner diameter |
| Choosing a decor tray for food | Finish not meant for food | Check the stated use |
| Oversizing for the ottoman | Tray tips when leaned on | Leave a margin |
Styling a 40 cm tray
A 40 cm tray is large enough for a grouping of three objects at different heights, the classic styling formula: a tall candle or vase, a medium stack of books or a small plant, and something low like a bowl or coasters. For serving, it holds four to six drinks comfortably, or a small cheese and fruit spread on a liner. Step up to 50 cm when you want space for a centerpiece plus room around it.
