Boeing 787-8 vs 787-9 vs 787-10: How to Tell Them Apart
The Boeing 787 Dreamliner is one of the most popular long-haul jets flying today. It comes in three variants — the 787-8, 787-9, and 787-10 — and at a distance, they can look identical. Same engine, same wing shape, same raked wingtips, same tinted windows.
But they're not the same. The differences are real, and once you know what to look for, you can call the variant from the ramp every time.
This guide is for spotters. No charts. No sales pitch. Just what your eye needs.

The Core Challenge: Everything Looks the Same
The 787 family shares these features across all variants — and none of them help you differentiate:
- GE GEnx-1B or Rolls-Royce Trent 1000 engines — same serrated chevron nacelles on all three
- Raked wingtips — no winglets, same on all three
- Tinted windows — the slightly larger, electrochromic dimming windows are on all three
- Nose profile — same rounded, somewhat blunt nose
- Carbon fiber composites — same smooth fuselage texture
So what does differ? Length — and therefore proportions.
The Primary ID Method: Body Length and Proportions
The three 787 variants are stretches of the same design. Think of them as the same template at three different sizes.
787-8: The Original
The 787-8 is the shortest and the one that entered service first, in 2011 with All Nippon Airways.
From the ground, the -8 has the most balanced proportions. The fuselage doesn't feel overly long relative to the wing span. The nose-to-wing and wing-to-tail sections look roughly equal in visual weight.
Quick ID cue: If you see a 787 and it looks "right-sized" — neither stubby nor stretched — it's probably a -8.
Operators to know: All Nippon Airways (ANA), Japan Airlines (JAL), Etihad Airways, LATAM, LOT Polish Airlines, Icelandair (often on transatlantic routes), Oman Air.
787-9: The Stretched Standard
The 787-9 is 6.1 meters longer than the -8 — roughly the length of a large SUV added to both ends of the fuselage.
At the gate, you'll notice the fuselage looks slightly elongated compared to what you'd expect. The wing appears to be set a bit further back along the body, and there's more tube ahead of and behind it.
The 787-9 is the most common variant in service. If you see a 787 and you're not sure, statistically it's a -9.
Quick ID cue: The -9 looks like the -8 but "stretched." The fuselage has more visual length relative to the wing span. The mid-cabin area feels longer when walking the jetway.
Operators to know: United Airlines (large fleet), Air New Zealand (flagship long-haul), Qantas, Singapore Airlines, Qatar Airways, Air Canada, Korean Air, British Airways.
787-10: The Long One
The 787-10 is the stretched-out workhorse — 68.3 meters long, making it 11.6 meters longer than the -8 and the longest 787 variant.
From the ramp, the -10 is clearly the longest. If you see a 787 and it strikes you as looking almost too long — like someone photoshopped extra fuselage into the middle — that's a -10.
The wing-to-fuselage ratio looks different from the other two variants. There's noticeably more fuselage fore and aft of the wing, and the landing gear looks slightly more substantial to handle the heavier MTOW.
Trade-off: The -10 gave up range for capacity. It can't do ultra-long-haul (no nonstop Sydney–London), which is why it typically flies medium to long-haul high-density routes.
Quick ID cue: Park it next to a -9 or anything else at the gate, and it looks big. It has the proportions of a widebody workhorse, not a sleek long-hauler.
Operators to know: United Airlines, Singapore Airlines, Scoot (LCC of Singapore), Etihad Airways, All Nippon Airways, Korean Air, Air France.
Side-by-Side Visual: What to Focus On
When you're at the fence line or shooting from the terminal:
1. Overall length impression
- Short and balanced = -8
- Normal stretched = -9
- Noticeably long = -10
2. Mid-fuselage "barrel" length Count the window rows if you can. The -8 has around 34–36 economy window rows in a typical 2-class config. The -9 has around 42–45. The -10 can push 50+. Window rows aren't always easy to count, but if you're looking at the side of the aircraft and it just keeps going... it's a -10.
3. Tail-to-wing gap The distance from the rear main door to the trailing edge of the wing increases with each stretch. On the -10, this tail section looks particularly long. Spot the overwing emergency exits, then look at how much tube is behind them.
The Engine Question: GEnx vs Trent 1000
All three variants can be ordered with either engine:
- General Electric GEnx-1B — smooth lower lip on the nacelle, chevrons at the exit
- Rolls-Royce Trent 1000 — slightly different inlet shape, same chevron pattern
Both look similar at distance. The GEnx has a slightly rounder, smoother inlet; the Trent 1000 inlet has a subtle "pinched" or oval quality when viewed head-on. Neither is a reliable differentiator between variants.
Helpful for operator ID: ANA operates both GEnx and Trent 1000 fleets. United's 787s are exclusively GEnx. Air New Zealand traditionally operates Trent 1000.
Common Scenarios: Field Identification
Scenario 1: Short-haul leisure route, single-aisle gates, holiday destination airport Unlikely to be any 787. But if it is, probably -8 or -9 on a medium-haul feeder.
Scenario 2: Transatlantic hub, widebody gates Strong chance it's a -9. United, Air Canada, Norwegian (legacy), British Airways all used -9s or -8s here.
Scenario 3: Intra-Asia high-frequency route (Tokyo–Singapore, Seoul–Singapore) Good candidate for -10. Singapore Airlines and ANA use -10s on dense Asia routes.
Scenario 4: Ultra-long-haul (NYC–Tokyo, London–Perth, Houston–Auckland) Almost certainly -8 or -9. The -10 doesn't have the range for true ULH.
Livery Tips: Know the Fleet Configs
Certain operators are almost exclusively one variant — which gives you a shortcut when you can ID the airline first:
| Airline | Primary 787 variant | |---|---| | Air New Zealand | 787-9 | | Scoot | 787-9 and 787-10 | | Icelandair | 787-9 | | LOT Polish | 787-8 and 787-9 | | Oman Air | 787-8 and 787-9 | | Singapore Airlines | 787-10 (medium-haul) | | Air France | 787-9 and 787-10 | | United Airlines | 787-8, -9, and -10 (largest 787 fleet outside Japan) |
When You're Completely Stumped
If you can't call it visually, fall back to:
- Airline Fleet pages — most airlines list aircraft types by route on their websites
- Flightradar24 — look up the flight and check the aircraft type (B788, B789, B78X — that last one is the ICAO code for -10)
- Aviation Spotter tool — upload your photo and let the AI identify it. Tail number → HexDB → aircraft registration → type
- Planespotters.net — tail number search gives you exact variant and age
The ICAO codes are helpful:
- B788 = 787-8
- B789 = 787-9
- B78X = 787-10 (the "X" covers the stretch)
Why the -10 Didn't Sell Better
A quick bit of trivia if you're at the fence: the 787-10 was the last to market and has the fewest orders of the three. The reason is that trade-off between capacity and range. For airlines doing true long-haul (think: Australia to Europe, New York to Tokyo), the -9 is the right tool. The -10 makes financial sense on routes like Singapore–Tokyo or Seoul–Bangkok where you want widebody comfort and density but not max range.
That also means the -10 tends to concentrate at specific hubs — Singapore's Changi is one of the best places on earth to see them regularly.
Put Your Eyes to Work
The 787 family is a masterclass in incremental design. Boeing stretched a winning formula and sold it to airlines across the globe. For spotters, that means the variants are subtle — but identifiable if you train your eye on length and proportion.
Next time you're at the fence:
- Is it a 787? → Check: raked wingtips, no winglets, serrated engine chevrons, tinted windows ✅
- Which variant? → Check: does the fuselage look balanced, slightly stretched, or noticeably long?
That's it. You don't need a tape measure.
