The three most common types of coffee cup lids are flat lids, which sit level with the rim and take a straw; dome lids, which rise above the rim to make room for whipped cream and toppings; and sipper lids, which have a raised spout for drinking hot coffee without a straw.
For coffee shops, choosing the right lid comes down to two questions: what is the drink, and what cup is it going in? In this blog, we’ll walk through each lid type, which drinks it suits, and how to make sure every lid fits the coffee cups you stock.
Flat Lids
Flat lids sit low and level across the cup rim, with a straw slot in the center. They are the everyday choice for iced drinks served with a straw: iced coffee, cold brew, iced tea, lemonade, and soft drinks. Because there is no extra space above the rim, a flat lid works best when the drink stops just below the top and carries no toppings.
That low profile pays off behind the counter, too. Flat lids stack neatly and are quick to grab during a rush, while a tight seal and the small straw-slot opening help keep cold beverages in the cup. Bubble tea shops using wider straws should test-fit them against the slot first.
At Sleeve a Message, our clear flat lids with a straw slot fit 12 to 24 oz clear PET cold cups with a 98mm rim.
Dome Lids
Dome lids rise above the cup rim, leaving extra space for whatever goes on top. That headroom keeps whipped cream, cold foam, drizzle, and blended drinks intact instead of pressed flat against the lid. Frozen coffee drinks and layered drinks hold their shape better under a dome.
The opening at the top takes a straw, so dome-lid drinks are just as easy to drink as flat-lid drinks. The difference is presentation. A clear plastic dome shows off the toppings and layers your team built, and with specialty drinks, how customers perceive the drink is part of what they are paying for.
Our clear PET dome lids snap onto 12 to 24 oz clear PET cold cups with a 98mm rim, the same cups our flat lids fit, so you can stock one cold cup and switch lids by drink.
Sipper Lids
Sipper lids are made for hot drinks. Instead of a straw hole, they have a raised spout, or drinking opening, that lets customers sip hot coffee, tea, and other beverages without taking the lid off. A small vent hole helps release steam and limits pressure buildup, so the coffee flows smoothly.
Sipper lids also have a slight dome that gives lattes, cappuccinos, and other specialty coffee a little room for foam. Paired with a secure fit on the cup rim, that design prevents spills on the way to the car or the office.
Our sipper dome lids come in white and black and fit our paper hot cups, with an 80mm lid for 8 oz cups and a 90mm lid for 12 to 24 oz cups. Since a hot cup with a sipper lid usually heads out the door, it pairs naturally with a coffee sleeve.
Dome Lid vs Flat Lid: Which Do You Need?
Both lids fit the same cold cups, so the choice depends on the drink type. Ask three questions:
- Does it have toppings? Whipped cream, cold foam, or a blended top needs a dome lid. If the drink stops below the rim, a flat lid does the job.
- Is it sipped through a straw? Both lids take one. If customers will sip a hot drink directly, neither lid is right. Reach for a sipper lid.
- How will it travel? Flat lids sit lower and fit more easily in carriers and delivery bags. Dome lids need more clearance but protect the toppings along the way.
Many coffee shops stock both and assign a lid type to each drink on the menu for consistent quality.
How to Match Lids to Your Cups
A lid only works if it fits, and the cup’s rim diameter and the beverage temperature it was made for decide that.
Start with lid diameter. Lids are sized to the cup mouth, not just the cup size, which is why one lid often covers several sizes. Our clear flat and dome lids fit 12 oz Squat to 24 oz clear PET cold cups with a 98mm rim, and our hot sipper lids fit paper hot cups at 80mm for 8 oz and 90mm for 12 to 24 oz.
Next, match the temperature. Use hot drink lids for hot cups and cold drink lids for cold cups. Lid materials and rim styles differ, so swapping them can cost you a secure seal.
The simplest way to get a tight seal every time is to order cups and lids together. Whether you are stocking plain cups or custom drink cups, ordering them as a set means every lid fits before the first rush.
Common Questions About Coffee Cup Lids
What is a dome lid?
A dome lid rises above the rim, leaving room for whipped cream, cold foam, and blended drinks. Dome lids for cold beverages are usually made of clear plastic and have a hole in the top for a straw. The clear dome also lets customers see the toppings and layers inside the cup.
What is a sipper lid?
A sipper lid is a hot cup lid with a raised spout that lets customers drink without removing the lid or using a straw. A small vent hole lets air in and steam out for a steady, controlled flow. Most sipper lids have a slight dome to leave room for foam on lattes and cappuccinos.
What are coffee cup lids called?
Coffee cup lids are usually named by shape and use. Flat lids sit level with the rim and have a straw slot. Dome lids rise above the rim to make room for toppings. Sipper lids, sometimes called sip lids, have a raised spout for hot drinks. You may also see them listed as hot cup lids, cold cup lids, or straw lids.
