“Larger” depends on what you measure. For cabin space, the clearest examples in the available manufacturer figures are Boeing’s BBJ 737 MAX and BBJ 777X aircraft and Airbus’s ACJ TwoTwenty. They are corporate aircraft derived from airline designs—not ordinary private jets—and the available figures do not establish a verified ranking of nine aircraft against the Global 7500. This guide separates documented cabin measurements from models for which a like-for-like comparison cannot be made.
What “larger than the Global 7500” means
An aircraft can be larger by cabin length, width, height, floor area, volume, exterior length or wingspan. Those measures are not interchangeable: a wider cabin may have more floor area without being longer, while a long fuselage does not by itself prove greater usable cabin volume. A fair comparison also needs the same measurement definitions and a Global 7500 baseline.
The manufacturer figures below offer useful scale comparisons, but they do not support a definitive nine-model ranking. They come from different manufacturers and documents, use different cabin metrics, and in one case describe an unfinished interior. No Global 7500 specification figure is included here for a matched calculation.
Aircraft with published cabin-space figures
Boeing BBJ 737 MAX 7, 8 and 9
Boeing lists cabin floor areas for three BBJ 737 MAX variants. It describes the MAX cabin as capable of offering more than twice the cabin volume of traditional long-range business jets; that is Boeing’s marketing claim, not an independent comparison specifically against the Global 7500.

| BBJ variant | Published cabin area | Source and qualification |
|---|---|---|
| 737-7 | 82 m² | Boeing Business Jets, current Government Transport page, accessed 2026; manufacturer figure. |
| 737-8 | 95 m² | Boeing Business Jets, current Government Transport page, accessed 2026; manufacturer figure. |
| 737-9 | 104 m² | Boeing Business Jets, current Government Transport page, accessed 2026; manufacturer figure. |
These are airline-derived corporate aircraft with cabin layouts selected for the individual aircraft. Cabin area does not tell you how much of that area will be available as living space after a particular fit-out.
Boeing BBJ 777-8 and 777-9
Boeing’s 2022 BBJ 777X one-pager gives cabin areas of 302.5 m² for the 777-8 and 342.7 m² for the 777-9. Boeing’s current product page describes up to 343 m² of cabin space and calls it “the largest cabin in business aviation”; that is the manufacturer’s description, not an independent category ranking. The 2022 model-specific values and current rounded maximum are not a like-for-like cabin-volume comparison with a business jet.
Airbus ACJ TwoTwenty
Airbus’s December 2024 light brochure lists the ACJ TwoTwenty’s unfinished cabin as 23.8 m long, 3.3 m wide and 2.1 m high, with a volume of 146 m³. “Unfinished” matters: these are not finished-interior dimensions, and a completed cabin’s usable space and layout depend on the fit-out. Airbus’s brochure compares the aircraft with the Global 7500, but the dimensions here should not be treated as an independent, matched measurement study.

Other plausible comparisons—and what is not established
Boeing BBJ 787 family
Boeing markets corporate versions of the 787-8, 787-9 and 787-10, but the reviewed product information does not provide model-level cabin dimensions. They are relevant examples of large airline-derived corporate aircraft, but the available figures do not establish how each compares with the Global 7500 on a defined cabin metric.
Airbus ACJ319
An Airbus comparison graphic depicts the ACJ319 footprint as wider than the Global 7500’s while showing similar parking-space length. That is an Airbus marketing graphic, not an independent measurement. It supports a qualified width comparison, not a claim that the ACJ319 is larger in every dimension or overall.
Gulfstream G700 and G800
Gulfstream publishes dimensions for both aircraft, but without a cited Global 7500 baseline in this comparison, neither can responsibly be labelled categorically larger. The G700’s published cabin length excluding baggage is 17.35 m, cabin volume 73.71 m³, exterior length 33.48 m and wingspan 31.39 m. For the G800, the corresponding figures are 14.27 m, 60.54 m³, 30.40 m and 31.39 m. Gulfstream identifies these as manufacturer specifications; they are useful reference points, not proof of a size ranking against the Global 7500.

Why a list of nine is not a reliable ranking
Nine entries can be assembled by counting the three BBJ 737 MAX variants, two BBJ 777X variants, three BBJ 787 variants and the ACJ TwoTwenty. But that count does not make nine verified larger aircraft: model-level dimensions are missing for the BBJ 787s, and the available evidence does not compare every candidate to the Global 7500 using one consistent metric. Counting subvariants as separate jets can also obscure the more useful distinction between aircraft families and individual configurations.
Recommended Free Tools
The BBJ 737 MAX and BBJ 777X figures do show cabins at a scale associated with airline-derived corporate aircraft. The ACJ TwoTwenty has substantial published unfinished-cabin dimensions. These are meaningful alternatives for readers asking about substantially more cabin space, but actual usable space depends on configuration and the comparisons should not be collapsed into one ranked score.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Business jets versus airline-derived corporate jets
The Global 7500 is a purpose-built long-range business jet. BBJ aircraft are Boeing airliners adapted for corporate or government use, and Airbus Corporate Jets are based on Airbus commercial aircraft. Their larger airframes can accommodate expansive bespoke interiors, but they are not simply standard private jets with an extra-large cabin: configuration, completion and operation are part of the aircraft choice.

Range is a separate decision axis, not a size measurement. Manufacturer range claims depend on mission assumptions, so figures from different makers should not be treated as equivalent without matching those assumptions. Buyers comparing cabins should also consider the completed layout, baggage space and usable room rather than relying on a single headline area or volume.
Can you charter an Airbus Corporate Jet?
Airbus’s iflyACJ directory identifies operators and specific charter aircraft, including ACJ319, ACJ320, ACJ330 and ACJ TwoTwenty examples. That makes charter a potential way to experience an ACJ, but a directory listing does not guarantee availability for a particular date, route or configuration. Confirm current aircraft, itinerary and booking terms directly with the operator.
