If you have a tumbler-type cup, choosing the right accessory can sometimes be confusing. This guide summarizes which accessory fits which size.
First, determine your tumbler's size
The most critical information for accessory compatibility is the tumbler's volume (oz). The most common sizes are:
- 20oz: compact for daily use
- 30oz: medium size
- 40oz: most popular, large size with a handle
Compatibility table
| Accessory | Compatible size | Note |
|---|---|---|
| Replacement lid (with flip straw) | Usually 40oz | Inner mouth diameter is important |
| Replacement lid with handle | 40oz | Carrying handle + flip straw |
| Silicone ice mold | 20/30/40oz | Ice sized to fit through the mouth |
| Tritan straw | Most sizes | Can be cut, adjustable |
| Base protector | 30/40oz | According to base diameter |
What to look for when choosing a replacement lid?
Two determining factors: inner mouth diameter and lid type. Most 40oz models have similar mouth measurements. Flip-straw and leak-proof lids are the most practical for on-the-go use.
Compatibility of ice molds and base protectors
An ice mold does not attach to the tumbler; what matters is the size of the ice it produces. Large, cylindrical ice cubes fit comfortably into tumblers with narrow openings. The base protector, on the other hand, fits the bottom diameter of the tumbler; the measurements for 30 and 40oz are different.
Frequently Asked Questions
Will a 40oz lid fit a 30oz tumbler?
Generally no; lids are produced according to the inner mouth diameter.
What if the straw is too long?
Tritan straws can be cut; you can shorten them to your desired length.
Which size is the ice mold suitable for?
It produces ice that fits 20/30/40oz tumblers.
Does the base protector fit every tumbler?
No; there are separate measurements for 30 and 40oz.
Key Points
- The most important information for accessory selection is the ounce measurement.
- Inner mouth diameter is decisive for lids.
