Choosing coffee cup lids by ounces alone is easy to get wrong. A 12 oz paper hot cup and a 12 oz PET cold cup may hold the same amount, but they do not use the same lid in these ranges. The reliable starting point is the lid size shown on the cup listing.
This guide compares the disposable paper cups and PET cold cups available from BIGSKU, including the matching hot lids, cold-lid profiles and case quantities to check before ordering.
This becomes useful when a counter carries several drink sizes or orders cups and lids separately. Keeping a clear size reference also makes repeat orders easier to review across locations.
Match Coffee Cup Lids by Listed Size, Not Capacity
Cup capacity tells you how much the cup holds, not which lid will fit. The correct lid depends on the dimensions and design of the specific cup line.
On the Paper Coffee Cup White listing, D80 and D90 are lid-size codes that correspond to the 80 mm and 90 mm options on the matching Coffee Cup Lid page. The PET cup range lists its compatible lids directly in millimetres.
| Cup capacity | Paper hot cup | PET cold cup |
|---|---|---|
| 8 oz | D80, matched to an 80 mm lid | 78 mm lid |
| 10 oz | D90, matched to a 90 mm lid | 78 mm lid |
| 12 oz | D90, matched to a 90 mm lid | 98 mm lid |
| 16 oz | D90, matched to a 90 mm lid | 98 mm lid |
| 20 oz | D90, matched to a 90 mm lid | 98 mm lid |
| 24 oz | Not offered | 98 mm lid |
The 12 oz row shows why capacity is not enough to complete an order. The paper cup takes a 90 mm hot lid, while the PET cup takes a 98 mm cold lid. Asking only for a lid for a 12 oz cup leaves out the detail that determines the fit.
For repeat orders, record the full cup name and its listed lid size rather than keeping only the capacity. If several cup lines are used, this gives staff a clearer reference and reduces the chance of treating every cup with the same ounce rating as interchangeable.
The paper cup range uses two lid sizes across five capacities. Its matching polypropylene lid is sold in 80 mm and 90 mm options, with 1,000 lids per case. Because the 10, 12, 16, and 20 oz cups all use the 90 mm option, one lid size can support several hot-cup capacities. Purchasing quantities should still reflect the cup mix used at each location.

Keep Hot and Cold Cup Lids Separate
The PET Cold Cup Clear is offered from 8 to 24 oz and uses 78 mm or 98 mm lids. These sizes do not overlap with the 80 mm and 90 mm hot lids, so the two systems should be ordered and stored separately.
Plastic coffee cup lids are not interchangeable simply because they look similar. The hot lid is white polypropylene, while the cold lids are clear PET. These visual cues can help staff organize stock, but they do not replace the size check. The cup listing remains the reference for compatibility.
Within these product lines, a hot lid should not be ordered for a PET cold cup, even when the cup capacities are the same. Confirming the cup type and lid size first is simpler than trying to correct a mismatched case after delivery.
Choose a Flat, Dome or Strawless Cold Lid
Once the cold-cup size is confirmed, the remaining decision is how the drink will be served. All three cold lid lines are made from PET and are listed at 1,000 lids per case.
| Lid profile | Available sizes | When to choose it |
| Flat Cup Lid Clear | 78 mm and 98 mm | For iced coffee, smoothies, juices and other cold drinks that do not need extra space above the rim. |
| Dome Cup Lid Clear | 78 mm and 98 mm | For drinks served with whipped cream, fruit, boba or other toppings above the rim. |
| Strawless Cup Lid | 98 mm only | For a sip-through format designed for drinking directly from the lid. |
The 78 mm cups can be paired with flat or dome lids. The 98 mm cups can use all three profiles, including the strawless option. This means a business using both cold-cup sizes may need more than one lid SKU, even when the drinks are served in the same way.
Review the drink menu before deciding how many profiles to carry. A flat lid may cover standard iced drinks, while a dome lid is useful when toppings extend above the rim. The strawless option changes how the drink is served, so it should be selected for the intended format rather than treated as another general-purpose 98 mm lid.
Matching Lids to Cups From Another Supplier
The size mappings in this guide apply to the cup and lid lines linked above. A cup from another supplier should be checked against its own product specifications. Capacity alone is not enough, and even products with the same nominal diameter may differ in rim shape or manufacturing tolerance.
Before placing a case order:
- Check the lid or rim size stated for the exact cup line.
- Confirm that the lid is intended for the cup material and beverage type.
- Verify compatibility with the cups already in stock.
- Do not assume that a hot lid and cold lid are interchangeable.
When cups and lids come from the same range, follow the matching-lid reference on the cup listing. This is more reliable than guessing from capacity or appearance.
Compare Cup and Lid Case Quantities
Matching the size does not necessarily mean the case quantities will match. The four lid lines in this guide are listed at 1,000 lids per case, while the number of cups can vary by selected capacity.
For example, the 24 oz PET cold cup is listed at 600 cups per case, while its 98 mm lids are listed at 1,000 per case. A one-case-to-one-case order would therefore leave 400 lids after the cup case is used. For this cup size alone, five cup cases and three lid cases contain the same number of units.
Before setting a reorder quantity, check the case count for the selected cup and lid, then account for any other cup capacities using the same lid. Existing stock and actual usage should determine the final order rather than a fixed one-to-one case ratio.
Keeping a separate reorder line for each cup capacity and lid size also makes it easier to see when one shared lid is supporting several cup formats.
Browse disposable cup lids to compare the hot, flat, dome and strawless options. If cups and lids are being restocked together, visit the to-go cups and lid accessories collection or contact BIGSKU about a volume order.
