Quick Verdict
IIT Bombay wins on faculty and academics: it consistently ranks higher in NIRF's Engineering category, sits in the "old IITs" tier known for broader course offerings and deeper research ecosystems, and offers a wider spread of core and emerging-tech branches. IIT Indore, one of India's newer IITs, is still a legitimate and improving Indian Institute of Technology (IIT — a network of government-run engineering and technology institutes across India), but the sourced data consistently places it several rungs below Bombay on ranking and breadth.

Detailed Analysis
On institutional ranking, IIT Bombay is unambiguously ahead, though the exact margin depends on which sourced table you look at — a discrepancy worth being upfront about. Buddy4Study's rendering of the NIRF Engineering Rankings 2025 places IIT Bombay 3rd and IIT Indore 12th, and separately notes that "IIT Madras, IIT Delhi, and IIT Bombay have retained the coveted 1st, 2nd and 3rd positions, respectively" for a seventh consecutive year, while also observing that "comparatively newer IITs like IIT Roorkee, IIT Hyderabad and IIT Indore have secured a high place in the rankings" for an institute of its age. A separate table sourced from Entri.app instead lists IIT Bombay 2nd (score 87.66) and IIT Indore 16th (score 72.00). Both tables agree on the broad picture — Bombay solidly top-3, Indore in the lower-teens — but disagree on the precise rank, likely reflecting different editions or methodologies of the ranking being scraped. Rather than pick one number as "the truth," both are reported here so readers can see the range.
Faculty and student-facing resourcing follows a general IIT-wide pattern rather than an Indore-specific one: across the IIT system, the faculty-to-student ratio runs between 1:6 and 1:8, with the system's Standing Committee prescribing a floor of 1:9 department-wise, and government funding to each IIT running between roughly ₹900–1,300 million a year, well above typical engineering colleges in India (Wikipedia). The sourced data doesn't break this ratio out separately for IIT Bombay versus IIT Indore specifically, so it's best read as context for the IIT system as a whole rather than a head-to-head number.
Where the two institutes visibly diverge is course breadth and campus scale. EarlyCareer.in's comparison of all IITs groups IIT Bombay among the "First Generation (Old 7)" IITs — alongside Delhi, Kanpur, and Madras — offering core branches like Computer Science, Electrical, Mechanical, Civil, and Chemical Engineering, plus emerging fields such as AI, Data Science, Quantum computing, and IoT. IIT Indore, grouped with Gandhinagar and Mandi as "Second Generation (2008–2012)" institutes, is shown offering a narrower core set (CSE, EE, ME) with emerging strengths in Cognitive Science and Earth Sciences instead. The same source's infrastructure table lists IIT Bombay's campus at 550 acres against IIT Indore's 501 acres — a much smaller gap than the academic-breadth difference suggests, meaning campus size alone doesn't explain the ranking or course-offering gap.
The source's own framing is candid about the tiering: it summarizes "Old IITs (Top 7) – More courses, global reputation, top placements" versus "Mid IITs (2nd Gen) – Well-rounded growth, emerging research" (EarlyCareer.in) — placing IIT Indore in a growth-stage bracket rather than the top tier IIT Bombay occupies.
Verdict
IIT Bombay wins on faculty and academics, backed by a consistently higher NIRF Engineering rank across two independently sourced tables (3rd or 2nd, versus IIT Indore's 12th or 16th), a broader spread of core and emerging-technology branches, and membership in the "Old 7" tier associated with deeper research ecosystems. IIT Indore is the runner-up — a genuine, improving IIT with a nearly comparable campus footprint (501 acres vs. 550) and its own emerging strengths in cognitive science and earth sciences. The one condition under which a reader should lean toward IIT Indore instead: if a specific niche field like Cognitive Science or Earth Sciences is your actual academic priority and it isn't offered at the same depth at Bombay, Indore's specialization there may matter more to you than its lower overall rank.
Frequently Asked Questions
Q: What is IIT Bombay's NIRF Engineering rank?
Sourced tables disagree slightly: 3rd per Buddy4Study and 2nd per Entri.app. Either way, it sits solidly in the top 3.
Q: What is IIT Indore's NIRF Engineering rank?
12th per Buddy4Study, or 16th per Entri.app — the two sourced tables don't fully agree on the exact number.
Q: Is IIT Indore considered an "old" or "new" IIT?
New — it's classified as a "Second Generation" IIT (2008–2012 wave), while IIT Bombay belongs to the original "First Generation" (Old 7) group, per EarlyCareer.in.
Q: How do their campus sizes compare?
IIT Bombay's campus is 550 acres versus IIT Indore's 501 acres — a fairly small gap, per EarlyCareer.in.
Q: Does IIT Bombay offer more branches than IIT Indore?
Yes, per the sourced comparison: Bombay's core lineup includes CSE, EE, ME, CE, and Chemical Engineering plus emerging fields like AI and Quantum computing, while Indore's core set (CSE, EE, ME) pairs with emerging strengths in Cognitive Science and Earth Sciences (EarlyCareer.in).
Q: What's the general faculty-to-student ratio across IITs?
Between 1:6 and 1:8 system-wide, with a prescribed floor of 1:9, per Wikipedia — this figure isn't broken out separately for Bombay versus Indore in the sourced data.
Q: Does IIT Indore have any distinct academic strengths?
The sourced data points to Cognitive Science and Earth Sciences as emerging-field strengths at IIT Indore, distinct from Bombay's AI/Data Science/Quantum/IoT focus (EarlyCareer.in).
Q: Why do two ranking sources disagree on the exact numbers?
The sourced facts don't explain the discrepancy directly; it likely reflects different editions, years, or methodologies behind each rendering of the NIRF data, so both are reported here rather than treated as a single confirmed number.
