Two economy seats sold under the same fare can differ by more than three inches of width and several inches of legroom. This page puts the numbers side by side: published economy seat width and pitch by airline and aircraft, taken from the airlines’ own specification pages, plus what those numbers mean for your knees and shoulders.
You will also learn how pitch and width are measured, why the same aircraft type can have different seats at different airlines, how to convert centimeters to inches (79 cm is about 31 inches), and how to pick a better seat before you pay for one.
Quick Answer
Most economy seats published by U.S. airlines are about 16 to 18.7 inches wide, with a range of roughly 15.5 to 19.3 inches, and about 30 to 32 inches of pitch. Extra-legroom rows usually add 2 to 6 inches of pitch but rarely add width. Figures vary by airline, aircraft and cabin configuration, so always check the seat map for your exact flight.
Key Takeaways
- Seat width is measured between the inside of the armrests; seat pitch is the distance from a point on one seat to the same point on the seat in front.
- In the airline data below, economy widths run from 15.5 inches (narrowest Southwest seats) to 19.3 inches (widest seats on American’s Embraer E175).
- Standard economy pitch is usually 30 to 32 inches (76–81 cm); 33 to 34 inches is comfortable for most tall travelers.
- Extra-legroom products add pitch, not width. Premium economy is the cabin that adds both.
- U.S. airlines must publish the narrowest and widest seat in each class for every aircraft type they fly, but there is still no general federal minimum seat width or pitch for comfort.
Airline Seat Width and Pitch Comparison Chart (2026)
The table lists only rows we could confirm on the airline’s own aircraft or seat-specification pages in late 2026. Ranges reflect the narrowest and widest seats in that cabin, which often differ by seat position, armrest type or cabin version. Figures vary by aircraft and configuration, and airlines retrofit cabins, so treat this chart as a starting point and confirm the seat map for your flight number.
| Airline | Aircraft | Economy seat width | Economy pitch | Extra-legroom pitch | Comfort verdict |
|---|---|---|---|---|---|
| Southwest | Boeing 737-700 | 15.5–17.0 in | 31–33 in | 35–36 in (Extra Legroom) | Narrow but decent legroom; fine for average height, OK for tall flyers in rows with 32–33 in |
| Southwest | Boeing 737-800 / 737 MAX 8 | 15.5–17.8 in | 31–32 in | 34 in (Extra Legroom) | Typical legroom; broad-shouldered flyers may want an aisle |
| American | Boeing 737-800 / 737 MAX 8 | 16.6–17.8 in | 30 in | 34 in (Main Cabin Extra) | Tight for tall flyers in Main Cabin; Main Cabin Extra helps |
| American | Airbus A321neo | 16.3–18.7 in | 30 in | 34–39 in (Main Cabin Extra) | Tight in Main Cabin; widths vary a lot by seat |
| American | Airbus A319 (Version 1) | 17.3–18 in | 30 in | 34 in (Main Cabin Extra) | Average width, tight pitch |
| American | Boeing 787-8 | 16.2–18.1 in | 31 in | 35–36 in (Main Cabin Extra) | Typical long-haul economy; Premium Economy is 38 in / 19 in |
| American | Boeing 777-300ER | 17 in | 31 in | See seat map | Typical long-haul economy |
| American (regional) | Embraer E175 | 18.2–19.3 in | 30 in | 34 in (Main Cabin Extra) | Wide 2-2 seats, tight pitch |
| Delta | Airbus A220-100 | 18.6 in | 30–32 in | 33 in (Delta Comfort) | One of the widest economy seats listed here |
| Delta | Boeing 737-900ER | 17.3 in | 30–32 in (varies by version) | 33–34 in (Delta Comfort) | Average; check which version you are on |
| Delta | Airbus A350-900 | 17.4 in | 31–32 in (79–81 cm) | 34 in (Delta Comfort) | Typical long-haul economy; Premium Select is 38 in / 18.5 in |
| Japan Airlines | Airbus A350-1000 | About 18 in (46 cm) | About 33–34 in (84–86 cm) | Premium Economy about 42 in | Roomy economy pitch; good choice for tall flyers |
The “comfort verdict” column is general guidance based on pitch and width, not an airline rating. A 6’4″ traveler with long thighs and a 5’10” traveler with broad shoulders will judge the same seat differently.
What the chart shows
- Width varies more within an airline than between airlines. American’s A321neo Main Cabin runs from 16.3 to 18.7 inches depending on the seat.
- Regional jets and the A220 can be wider. Delta lists 18.6 inches on its A220-100, and American lists up to 19.3 inches on its E175, both in layouts with no middle seat on at least one side.
- Pitch is tightest on dense domestic narrowbodies. American’s 737 and A321neo Main Cabin are 30 inches, while Southwest and Delta often list 31 to 32 inches.
- Long-haul economy is not automatically roomier. Delta’s A350 Main cabin is 17.4 inches wide, narrower than its A220.

How Seat Pitch Is Measured
Seat pitch is measured from any point on one seat to the same point on the seat directly in front of it. Southwest uses exactly that manufacturer definition on its seat-specification page. Because the two reference points are on identical seats, pitch is really the spacing between rows.
That is why pitch is not the same as legroom. A 31-inch pitch does not give you 31 inches of open space: part of it is taken up by your own seat cushion and the seatback in front of you. Two rows with identical pitch can feel different because of:
- Seatback thickness. Slimline seats leave more knee room at the same pitch.
- Literature pockets and tray tables. A bulky pocket at knee height can cost an inch or more.
- Under-seat boxes. Entertainment or power equipment can shrink foot space.
- Recline. When the seat in front reclines, your upper-body and laptop space drops.
Airlines mount seats on floor tracks, so they can move rows closer together or farther apart without changing the aircraft. That is how one airline can fly the same model at 30 inches while another installs 32 inches, and why the same airline may run several versions of one aircraft type, as Delta does on its 737-900ER.
Converting pitch from centimeters
Many international airlines publish pitch in centimeters. Divide by 2.54 to get inches:
- 71 cm = about 28 in (very tight)
- 76 cm = about 30 in
- 79 cm = about 31 in (standard economy)
- 81 cm = about 32 in
- 84 cm = about 33 in
- 86 cm = about 34 in
What Seat Pitch Is Good? A Comfort Guide by Height
There is no official comfort standard, but the published numbers line up with real-world experience fairly consistently. Use this table to judge a number before you book.
| Published pitch | In centimeters | What it usually means | Average height (about 5’9″ / 175 cm) | Tall (6’2″ / 188 cm and up) |
|---|---|---|---|---|
| 28–29 in | 71–74 cm | Tightest economy layouts | Usable on short hops, cramped beyond 2 hours | Knees likely touch; avoid if you can |
| 30 in | 76 cm | Common on dense U.S. narrowbodies | Acceptable for most domestic flights | Tight; aim for an extra-legroom or exit row |
| 31–32 in | 79–81 cm | Standard economy on many aircraft | Comfortable enough for most trips | Workable with a slim seatback; better in an aisle seat |
| 33–34 in | 84–86 cm | Extra-legroom rows, roomier economy | Comfortable | Generally comfortable |
| 35–39 in | 89–99 cm | Extra-legroom products, some premium economy | Roomy | Roomy |
| About 42 in | About 107 cm | Long-haul premium economy (example: JAL A350-1000) | Very roomy | Very roomy |
Is 33 inches of pitch good? Yes. It is above standard economy on most U.S. aircraft and comparable to many extra-legroom rows; Japan Airlines’ A350-1000 offers about 33 to 34 inches in regular economy. Is 28 inches good? It is the tightest pitch you are likely to see; tolerable for an hour, uncomfortable for anyone tall. Is 79 cm (31 inches) enough for a 178 cm (5’10”) traveler? Usually yes for typical flights, especially with a slim seatback, though your knees may be close to the seat in front if it reclines.
If you want 33 inches or more, look for an extra-legroom product (Main Cabin Extra, Delta Comfort, Southwest Extra Legroom), an exit row, or an airline and aircraft whose standard economy is already roomier.
How Seat Width Is Measured, and Why It Varies
Under the Federal Aviation Administration’s seat-dimension disclosure rule, the width of a passenger seat means the distance between the inside of the armrests. Each U.S. airline with a website must publish the width of the narrowest and widest passenger seats in each class of service for every airplane make, model and series it operates. That rule is why many airlines show a range (such as Southwest’s 15.5 to 17.8 inches) rather than one number.
Why does width vary among airlines for the same aircraft type? The cabin is the same size, but each airline chooses its own seat model, armrest design, aisle width and number of seats per row. Within one aircraft, window seats can lose space to the curved sidewall, bulkhead and exit rows often have tray tables stored in fixed armrests, and some layouts use slightly different widths for aisle, middle and window seats.
What is a typical seat width?
Across the airline data in our chart, most economy seats fall between about 16 and 18.7 inches. A width of 18.8 inches would be above the widest standard economy seats listed by most U.S. mainline carriers and similar to the wider regional and A220 seats. Premium economy adds width: American’s 787-8 Premium Economy is 19 inches, and Delta’s A350 Premium Select is 18.5 inches.
Airlines rarely publish seat cushion depth or aisle width, so be wary of charts that list a single “average” for those measurements. If seat depth or aisle width matters for a mobility need, ask the airline’s accessibility desk for the specific aircraft.
Is there a minimum seat width or pitch?
Not for comfort. The FAA requested public comments on minimum seat dimensions needed for safe evacuation in 2022, after Congress directed it in 2018 to set rules. Current federal rules focus on evacuation: aircraft with more than 44 passenger seats must show that a full cabin can be evacuated within 90 seconds under simulated emergency conditions. The width disclosure rule tells you what you are buying, but it does not set a floor.
Premium Cabins: When the Numbers Change
Domestic first class is typically 20 to 21 inches wide with 37 inches or more of pitch. Delta, for example, lists one 737-900ER First Class version at 21 inches wide with 45 inches of pitch, which is the kind of spec behind searches for a “21-inch seat with 45 inches of legroom.” Lie-flat business class is usually described by bed length instead of pitch; Delta lists its A350 Delta One beds at 76 to 77 inches.
Premium economy sits between the two: about 38 inches of pitch on American’s 787-8 and Delta’s A350, and about 42 inches on Japan Airlines’ A350-1000.
Seat Pitch and Width Then and Now
People often ask what seat pitch looked like in the 1970s. Comparisons are tricky, because older figures came from different aircraft, layouts and measurement habits, and many claims online are not sourced. Our article on whether 1970s economy seats were really 20 inches wide looks at that history in detail. What is clear today is that dense domestic layouts commonly run 30 inches of pitch, while seat width depends far more on aircraft type and seat model than on the decade.
How to Find a Wider or Roomier Seat
- Check the operating airline and aircraft. Codeshare flights use the operating carrier’s seats.
- Open the airline’s aircraft page. American, Delta and Southwest all publish pitch and width by aircraft.
- Compare extra-legroom options. See our guides to American Airlines exit row seat prices and Delta preferred seating.
- Use seat type to your advantage. Aisle seats give shoulder and leg room into the aisle; exit rows add pitch but may have fixed armrests and eligibility rules.
- Know the low-cost tradeoffs. Some budget carriers use pre-reclined or limited-recline seats; our piece on whether Frontier Airlines seats recline explains what that means in practice.
- Recheck before departure. Aircraft swaps happen. On Southwest, our Southwest assigned seating guide explains which fares let you choose Extra Legroom seats.
Health tip: On flights longer than about four hours, the CDC notes that any traveler can be at risk of blood clots. Move your legs often, walk every 1 to 2 hours when it is safe, and talk to a doctor before travel if you have extra risk factors.
Frequently Asked Questions
What is the average size of an airplane seat?
In the airline data we checked, most economy seats are about 16 to 18.7 inches wide between the armrests, with a full range of 15.5 to 19.3 inches, and have about 30 to 32 inches of pitch. Extra-legroom rows typically offer 33 to 36 inches of pitch. There is no single standard size, so check the airline’s aircraft page for your flight.
How do you measure seat pitch on an airliner?
Seat pitch is measured from any point on one seat to the same point on the seat directly in front of it, so it equals the spacing between rows. It does not measure open legroom, because your own seat and the seatback ahead take up part of that distance. Seatback thickness, pockets and recline all change how roomy a given pitch feels.
Why does seat width vary among airlines for the same aircraft type?
Each airline chooses its own seat model, armrest design, aisle width and number of seats per row, so the same fuselage can hold different seats. Within one aircraft, window seats can lose space to the curved wall, and bulkhead or exit rows often store tray tables in fixed armrests. That is why airlines publish narrowest and widest widths.
Is 79 cm seat pitch good?
Yes, 79 cm is about 31 inches, which is standard economy pitch on many aircraft, including the low end of Delta’s A350 Main cabin. Most travelers of average height find it acceptable. A 178 cm (5’10”) traveler can usually sit comfortably, though knee room gets tight if the seat in front reclines. Taller travelers should look for 33 inches (84 cm) or more.
If I want 33 inches of pitch, which seat should I book?
Book an extra-legroom product or a roomier standard cabin. American’s Main Cabin Extra is 34 inches on its 737s, Delta Comfort is 33 to 34 inches on many aircraft, Southwest’s Extra Legroom seats are 34 to 36 inches, and Japan Airlines’ A350-1000 economy is about 33 to 34 inches. Confirm the pitch on the airline’s aircraft page before paying.
What is the minimum seat pitch for an average person?
There is no official minimum for comfort. As a practical guide, 30 inches is workable for most average-height travelers on domestic flights, 31 to 32 inches is comfortable for most trips, and 28 to 29 inches feels cramped beyond a short flight. U.S. rules require airlines to publish seat widths but do not set a general minimum pitch.
How wide are Southwest Airlines seats?
Southwest lists seat widths of 15.5 to 17.0 inches on its Boeing 737-700 and 15.5 to 17.8 inches on its 737-800 and 737 MAX 8. Standard and Preferred seats have 31 to 33 inches of pitch on the 737-700 and 31 to 32 inches on the larger jets, while Extra Legroom seats have 34 to 36 inches.
How wide are airplane seats from armrest to armrest?
Under the FAA disclosure rule, seat width is the distance between the inside of the armrests, and that is what airlines publish. Economy seats in our chart range from 15.5 to 19.3 inches, domestic first class is usually 20 to 21 inches, and premium economy on long-haul aircraft is about 18.5 to 19 inches.
