Napkin Sizes Explained: Open vs Folded Dimensions (Complete Guide)

Ordering paper napkins looks simple until someone asks for “20×20” and two very different products fit the description. One is a small cocktail napkin. The other is a large dinner napkin folded in four. They differ by roughly four times in surface area, and the mistake usually surfaces on the morning of the event.

This guide has napkin sizes explained the way a supplier explains them internally: every dimension in centimeters, always stated open, with the folded size you will actually see on the table alongside it. By the end you will know which size belongs on a cocktail tray, which belongs under a dinner plate, and how to phrase your order so nobody has to guess.

The one rule that prevents most mis-orders

Paper napkin sizes are always quoted as open dimensions in centimeters. The napkin arrives folded in cross — folded in four — so the size you see stacked on the table is a quarter of the surface area, and half of each stated side.

A 33×33 napkin is a 16.5×16.5 square once folded. A 40×40 napkin is a 20×20 square once folded. That second example is exactly where the confusion starts, because a genuinely small cocktail napkin is also sold as “20×20” — measured open.

So when anyone says 20×20, there are two candidates:

• Small cocktail — open 20×20 cm, folded 10×10 cm. The smallest standard size.
• Large dinner, folded — open 40×40 cm, folded 20×20 cm. Roughly four times the surface area of the cocktail napkin.

The fix is trivial: say the open size and the fold together. “40×40 open, folded to 20×20” cannot be misread. At Napki we ask this question systematically on every inquiry that mentions 20×20, whether it comes through the price calculator or the chat.

Every standard napkin size, open and folded

Here is the full range in a single table, with the use case each size is built for. Inches are rounded to one decimal. If you usually shop by US party-supply labels, 33×33 cm (about 13 in square) is close to what is sold as a luncheon napkin, and 40×40 cm (about 15.7 in) sits near the smaller dinner napkins.

Open size	Folded size	Common name	Typical use
20×20 cm (7.9 in)	10×10 cm (3.9 in)	Small cocktail	Cocktails, finger food, welcome drinks
24×24 cm (9.4 in)	12×12 cm (4.7 in)	Medium cocktail	Bars, cafes, coffee service
30×30 cm (11.8 in)	15×15 cm (5.9 in)	Small dinner	Lunch service, casual dining
33×33 cm (13 in)	16.5×16.5 cm (6.5 in)	Standard dinner	Sit-down restaurants — the most popular size
40×40 cm (15.7 in)	20×20 cm (7.9 in)	Large dinner	Fine dining, hotels, weddings
Kangaroo fold	Pocket format	Cutlery pocket	Premium hospitality, place settings

The Kangaroo fold sits slightly outside the grid because it is defined by its fold rather than by a square. It is typically built on 33×33 or 40×40 paper and folded into a pocket that holds the cutlery, so the whole place setting arrives as one piece. You can see the full breakdown on our napkin sizes page, which lists the same dimensions with visual references.

How to choose: match the size to the service, not to the budget

The instinct is to pick the cheapest size that fits. That works against you, because a napkin that is too small reads as cheap to your guest long before they think about your prices. Match the size to the service format instead.

1. Cocktail bar and finger food → 20×20 or 24×24. Guests hold the napkin, they do not lay it on a lap. Small is correct here, not a compromise.
2. Café and takeout → 24×24 or 30×30. Enough to wrap a pastry or handle a coffee cup without bulk.
3. Casual lunch service → 30×30. Comfortable in the hand, noticeably lighter on cost than the standard dinner size at volume.
4. Sit-down restaurant → 33×33. The default for a reason: it covers a lap and it folds well.
5. Fine dining, hotel, wedding → 40×40, or the Kangaroo fold. The extra surface reads as generosity. It is also the size that carries an elaborate fold without collapsing.

A worked example. A restaurant serving 90 covers a day orders 33×33 Double Point with a single-ink logo — the classic hospitality configuration. They use roughly two napkins per cover, which is about 5,400 napkins a month. Ordering 6,000 at a time covers the month with a small buffer and lands well inside the volume tiers. Their cocktail bar downstairs runs a separate 20×20 Full Color print, because the bar design is a four-color illustration that spot printing cannot reproduce.

Size affects your print options, not just your table

This is the part most size guides skip. The dimension you pick interacts with how your design can be printed.

• Full Color (digital CMYK) reproduces photos, gradients and complex multi-color logos, and works from 20 units — but only on white napkins, because the CMYK process needs a white substrate.
• Deluxe 1-ink prints a single spot color on white or colored napkins, from 100 units, with a one-off printing plate fee of $49.09.
• Deluxe 2-inks adds a second spot color, from 100 units, with a one-off plate fee of $98.18.

A large 40×40 napkin gives a detailed design room to breathe. A 20×20 cocktail napkin does not, which is why intricate logos shrink into mush at that size and a simplified mark works better. Our printing inks guide sets out the full decision matrix if your design is on the complicated side.

Size and paper quality are separate decisions

Two napkins at 33×33 can feel completely different depending on the paper underneath. There are four qualities to choose from, although not every quality comes in every size:

• 2-ply — two layers of soft tissue. The everyday standard for casual bars, takeout and high-volume events.
• 3-ply — three layers, noticeably thicker and more absorbent. Mid-range restaurants and corporate events that want a perceptible step up.
• Double Point — 2-ply with an embossed border on two opposite edges. The embossing adds visual texture and locks the layers together so they do not separate in use. A sit-down restaurant classic.
• Airlaid — a specialty non-woven paper that feels and drapes almost like fabric. The wedding and fine dining choice, and the most expensive of the four: a 40×40 cm Airlaid napkin in Full Color is $1.0041 each at 100 units and $0.4476 at 2,000, before shipping and US import duties.

On the current rate card, 2-ply and 3-ply come in every size from 20×20 to 40×40, Double Point in 20×20, 33×33 and 40×40, and Airlaid in 20×20 and 40×40. The pairing that trips people up is a large size in a thin quality. A 40×40 napkin in basic 2-ply feels flimsy precisely because there is more of it to feel. If you are going large, go at least Double Point. Our paper qualities guide walks through each one with its use case.

What napkin sizes cost

Unit prices are driven by four variables: size, paper quality, printing type and quantity. Size is genuinely one of the smaller levers — quantity moves the price far more.

Some reference points from the current US rate card, all in 2-ply Full Color: 500 units of 33×33 cost $0.5015 each ($250.75), and the same napkin at 10,000 units costs $0.2235. At 500 units, 20×20 is $0.4179 and 40×40 is $0.5433, which shows how little size moves the price. None of these include shipping or US import duties.

Two costs sit outside the unit price and are worth planning for: shipping goes by FedEx and is priced per box, flat to the 48 contiguous states — a small box is $138.00 Economy or $184.00 Priority and a large box $161.00 or $224.25, with the number of napkins per box depending on the size and paper quality — and the Deluxe printing plate ($49.09 for one ink, $98.18 for two) is charged once on your first order and reused free of charge on every subsequent run of the same design. Alaska, Hawaii and Puerto Rico are quoted separately. Import duties, the Merchandise Processing Fee and any state or local taxes are paid by the buyer on arrival (DAP).

Ordering: how to phrase it so nothing gets lost

When you send your request — by chat, by email or through the quote form — include these five things and your order cannot be misread:

1. Open size in cm, plus the folded size if you know it (e.g. “40×40 open, 20×20 folded”).
2. Paper quality: 2-ply, 3-ply, Double Point or Airlaid.
3. Printing type: Full Color, Deluxe 1-ink or Deluxe 2-inks — and the napkin color if it is not white.
4. Quantity, remembering the minimums: 20 units on Full Color, 100 units on Deluxe.
5. Your deadline, so we can tell you whether a longer lead time earns you a discount.

That last point matters more than people expect. Standard delivery takes 10 business days from proof approval with FedEx Priority, or about 14–16 with Economy, US customs clearance included. If you can wait longer, the discounts are automatic: 30 business days takes 5% off, 50 business days takes 10% off, and 60 business days takes 15% off. On a large hospitality order that is real money for doing nothing but planning earlier.

Frequently asked questions

What is the standard napkin size? 33×33 cm open, which folds to 16.5×16.5 cm. It is the most popular size for sit-down restaurants and the size most restaurants start from.

Why is 20×20 ambiguous? Because two different products carry that label. One is the small cocktail napkin measured open (20×20 open, 10×10 folded). The other is the large dinner napkin measured folded (40×40 open, 20×20 folded). Always state the open size and the fold together.

Are napkin sizes given open or folded? Open, always, in centimeters. Most paper napkins are folded in cross — in four — so the folded square is half of each stated side.

What size napkin should a cocktail bar use? 20×20 or 24×24. Guests hold these napkins rather than laying them on a lap, so the smaller formats are the correct choice, not a downgrade.

What is a Kangaroo fold napkin? A napkin folded into a pocket that holds the cutlery, typically built on 33×33 or 40×40 paper. It is used in premium hospitality where the whole place setting is delivered as a single piece.

Can I get any size in any paper quality? Not every combination. 2-ply and 3-ply come in every size from 20×20 to 40×40. Double Point comes in 20×20, 33×33 and 40×40, and Airlaid in 20×20 and 40×40. The combination you pick determines the unit price.

What is the minimum order for custom napkins? 20 units on Full Color digital printing, which prints on white napkins. Deluxe printing with one or two inks starts at 100 units.

Can I see the sizes before I order? Yes. The free sample pack contains five napkins in three finishes plus a size guide. You only pay the shipping, charged as one small box: $138.00 Economy or $184.00 Priority.
