If the NOBL All-in-One is already on your shortlist, the important question is not simply whether it is sold as a carry-on. What matters at the airport is whether its full outside dimensions match the published limit of the airline you actually use.
NOBL’s U.S. product information currently lists the All-in-One at 20.5 × 15.5 × 10 inches and says those dimensions exclude the wheels. [1] An independent Yahoo Shopping test measured its sample at roughly 23.25 × 15.5 × 9.5 inches. [3] That difference becomes important when your airline counts wheels and handles.
Quick Answer
Using the independently measured 23.25 × 15.5 × 9.5-inch sample, the NOBL All-in-One falls within the current published 24 × 16 × 10-inch limits for Southwest and Frontier. The same sample exceeds at least one published dimension for Delta, American Airlines, JetBlue and Air Canada. [3] [4] [5] [6] [7] [8] [9]
That is a comparison with published size rules—not a guarantee that a particular gate agent will accept or reject the bag.

What Size Does NOBL Actually Publish?
NOBL’s U.S. information lists the All-in-One at 20.5 × 15.5 × 10 inches with 35L capacity and says those dimensions exclude the wheels. [1]
The complication is that NOBL’s European page lists the equivalent 52.07 × 39.37 × 25.40 cm measurements and states that its dimensions include wheels. [2] Because those descriptions differ, the product-page figure alone is not enough for a strict airline-size decision.
| Source | Size | Wheel Information |
|---|---|---|
| NOBL U.S. | 20.5 × 15.5 × 10 in | Wheels excluded |
| NOBL Europe | 52.07 × 39.37 × 25.40 cm | Wheels included |
| Yahoo Shopping test | 23.25 × 15.5 × 9.5 in | Physical sample measurement |
What Changes When the Full Suitcase Is Measured?
Yahoo Shopping’s 2026 review physically measured its NOBL All-in-One sample at approximately 23.25 × 15.5 × 9.5 inches. The reviewer linked much of the extra height to the wheels. [3]
Against a common 22 × 14 × 9-inch airline maximum, that particular sample is about 1.25 inches taller, 1.5 inches wider and 0.5 inch deeper.
This does not prove that every NOBL unit has exactly the same measurements. It does show why full travel size versus the airline limit is a more useful comparison than shell dimensions alone.
Will the NOBL Carry-On Meet Major Airline Size Limits?
The comparison below uses the independently measured 23.25 × 15.5 × 9.5-inch sample.
| Airline | Published Maximum | Comparison |
|---|---|---|
| Delta [4] | 22 × 14 × 9 in | Exceeds published maximum |
| American Airlines [5] | 22 × 14 × 9 in | Exceeds published maximum |
| JetBlue [6] | 22 × 14 × 9 in | Exceeds published maximum |
| Southwest [7] | 24 × 16 × 10 in | Within published maximum |
| Frontier [8] | 24 × 16 × 10 in | Within published maximum |
| Air Canada [9] | 21.5 × 15.5 × 9 in | Exceeds published maximum |
Does Fitting in the Overhead Bin Mean the Bag Is Compliant?
Not necessarily. Physical overhead-bin fit and compliance with an airline’s published maximum are two different questions.
A suitcase can physically fit inside a bin while still being larger than the carrier’s stated dimensions. Aircraft type, available overhead space and gate enforcement can also change the real-world result.
This is also what travelers are asking about. One Reddit buyer questioned how NOBL’s listed dimensions compared with a 22 × 14 × 9-inch rule and planned to measure the suitcase after delivery. [10] Another 2026 discussion asked which airlines travelers had used with NOBL beyond Southwest and Frontier. [11]
Those posts are anecdotal rather than airline policy, but they validate the practical concern behind this search: will this suitcase create a size problem when I fly?
Which NOBL Carry-On Do You Actually Have?
Not every NOBL carry-on uses the same dimensions. NOBL also sells a separate All-in-One 19-inch model. [12] That means a measurement for the standard All-in-One should not automatically be applied to another NOBL model.
Before using any airline-size comparison, confirm the exact model name, whether its listed dimensions include wheels and whether the suitcase is expanded.
How Should You Measure Your NOBL Before a Flight?
- Stand the suitcase upright on its wheels.
- Measure from the floor to the highest fixed point.
- Measure across the widest outside points.
- Measure the deepest outside points, including fixed protrusions.
- If the case expands, measure it in the state you intend to travel with.
- Compare all three figures with your airline’s current published limit.
What Should You Do Before Buying or Flying?
If you already own the NOBL, your own full outside measurement is more useful than relying only on a product-page figure.
If you are still deciding whether to buy, start with the airline you use most often. A traveler regularly flying with a 24 × 16 × 10-inch allowance is dealing with a different size constraint from someone whose airline publishes 22 × 14 × 9 inches.
The practical rule is simple: choose the suitcase against your airline’s actual published limit—not just the word “carry-on.”

NOBL Carry-On Size FAQs
Is the NOBL All-in-One 22 × 14 × 9 inches?
No. NOBL’s U.S. information lists the standard All-in-One at 20.5 × 15.5 × 10 inches excluding wheels, while Yahoo Shopping measured its tested sample at about 23.25 × 15.5 × 9.5 inches. [1] [3]
Do NOBL’s listed dimensions include the wheels?
NOBL’s U.S. information says the listed dimensions exclude wheels, while its European page says the equivalent figures include them. Because those descriptions differ, measuring your own suitcase is the safer approach. [1] [2]
Does the NOBL meet Southwest or Frontier’s size limit?
Using Yahoo Shopping’s measured sample, it falls within both airlines’ current published 24 × 16 × 10-inch dimensional limits. That is a size comparison, not a guarantee of boarding acceptance. [3] [7] [8]
