Coolife Luggage Sizes: What 20, 24 and 28 Inches Really Mean
By Brandon Schultz Published
A Coolife "28-inch" suitcase stands about 30 inches tall. A "20-inch" one is about 22. The size name is a rough class, not a tape-measure reading. Coolife's measurements include the wheels and handles, and they shift a little between collections. Here are the real numbers, and what they mean at the check-in desk.
The three sizes, measured
Coolife gives the most complete figures for its ABS 3-Piece Set, Spinner + TSA, measured with wheels and carry handles:

| Size name | Width x depth x height | Width + depth + height |
|---|---|---|
| 20" (small) | 15.4 x 8.7 x 22.4 in | 46.5 in |
| 24" (medium) | 17.7 x 9.8 x 26.4 in | 53.9 in |
| 28" (large) | 20.9 x 11.4 x 30.3 in | 62.6 in |
| 28" expanded | 20.9 x 12.6 x 30.3 in | 63.8 in |
Coolife says the whole set weighs 25 lb. It doesn't give a weight for each piece.
Other collections land close by. The 24" ABS+PC Hardshell, Apricot Black gives its 24" as 17.3 x 9.8 x 26.4 in and its 28" as 20.5 x 11 x 30.3 in. The 20" PC+ABS Carry-On, Black Brown is 15 x 8.5 x 21.7 in and weighs 7 lb. Go by the exact case you're looking at, and ignore the size name.
Which sizes expand
In the 3-piece sets, only the 28" expands, and it adds about 15% space. Coolife says the 20" and 24" are non-expandable for a more compact design. That holds for the ABS set and the PC+ABS 3-Piece Set, 20/24/28. One exception: Coolife says 20" cases in colors marked "2.0" expand by 20%. Check the color name before you count on extra room.
The 20": your cabin bag
The 20" is the size Coolife sells as a carry-on. Its exact fit depends on the airline and the specific case. Our carry-on size guide compares airline limits and Coolife cabin bags in detail.
The 24": the medium checked bag
At 53.9 in all round, the 24" sits well under the 62-inch total that American and United publish for a standard checked bag. That gives you room to pack fully without worrying about size. Weight is the limit you'll hit first. Both airlines set 50 lb per economy bag, and a medium case filled with dense items can get there.
The 28": check the expansion before you fly
This is the one to measure. American adds up length, width and height to set its 62-inch (158 cm) checked-bag limit. United allows 62 total inches, wheels and handles included. On Coolife's own figures:
- The ABS set's 28" adds up to 62.6 in closed and 63.8 in expanded. Both are just over 62.
- The Apricot collection's 28" adds up to 61.8 in, just under.
So with the 28", it's the zipper rather than the packing that can tip it over. Fly it closed if you're near the line, and ask your airline how strictly it applies the limit. Weight matters even more here, because a full 28" can easily pass 50 lb.
Quick check before you pack
- Find the dimensions for your exact collection on its product page. Don't go by the size name.
- Add width, depth and height. For a 28", add the expanded depth too.
- Compare the total with your airline's own checked-bag page. American and United both use 62 inches.
- Weigh the packed case at home. Both set 50 lb for an economy bag.
