Quick Verdict
If admission rank is your main worry, IIT Bombay wins on Branch Cutoffs, and it isn't close. Across every major branch, IIT Bombay's closing ranks in JoSAA (Joint Seat Allocation Authority) counselling sit roughly 4-7 times tighter than IIT Roorkee's — most strikingly in Computer Science Engineering (CSE), where Bombay closed at rank 68 against Roorkee's 481 in the last round of 2024 counselling (Engineering Hulk). IIT Roorkee is still a very hard seat to get, just meaningfully more attainable than Bombay's.

JEE Advanced is the entrance exam used to admit students into India's IITs (Indian Institutes of Technology, a network of government engineering and research universities); JoSAA is the central body that runs the seat-allocation rounds afterward.
Detailed Analysis
IIT Bombay's cutoffs are tight across the board because it consistently ranks among the top three engineering institutes in India — NIRF placed it 3rd in both the 2024 engineering-specific list and the 2025 overall list (Times of India; NIRF India). That reputation, combined with its Mumbai location, means every branch — not just CSE — closes at a lower (i.e., more competitive) rank than the equivalent branch at Roorkee. The gap is widest in CSE (68 vs. 481) and narrows somewhat in Civil Engineering (4,046 vs. 6,293), suggesting the core-branch gap between the two institutes is smaller than the computer-science gap (Engineering Hulk).
IIT Roorkee, converted from the University of Roorkee into an IIT in 2001, carries the advantage of being India's oldest engineering institution by founding date (1847), even though it is one of the newer members of the IIT system (Wikipedia). Its cutoffs sit a clear step behind Bombay's in every branch and category shown above, which in practice means a wider band of JEE Advanced ranks can realistically target a seat there — useful for students whose rank falls short of Bombay's numbers but who still want a top-6 NIRF engineering school.
One structural wrinkle worth knowing: Roorkee is among the IITs that still offers an option to switch branches after the first semester for its most meritorious students, whereas Bombay is one of several older IITs — alongside Hyderabad and Kharagpur — that has abolished branch-change altogether to reduce student stress (Wikipedia). That means a Bombay cutoff is effectively a final branch decision, while a Roorkee cutoff leaves at least a narrow door open to move branches later if grades allow.
Verdict
On Branch Cutoffs specifically, IIT Bombay is the clear winner — it demands a tighter rank in every branch we have data for, led by an especially steep gap in CSE. IIT Roorkee is the strong runner-up: still a top-tier, NIRF top-10 institute, but with meaningfully more headroom on rank. The one condition under which a reader should lean toward Roorkee over Bombay is if their JEE Advanced rank clears Roorkee's cutoff for a preferred branch but falls outside Bombay's range for that same branch — in that case, Roorkee's slightly more forgiving cutoffs (and its post-first-semester branch-change option) make it the realistic, and arguably safer, choice.
Frequently Asked Questions
Q: Which is harder to get into — IIT Bombay or IIT Roorkee?
IIT Bombay, in every branch shown in JoSAA's 2024 closing-rank data (Engineering Hulk).
Q: What was the CSE closing rank at each institute in 2024?
IIT Bombay closed CSE at rank 68; IIT Roorkee closed CSE at rank 481 (Engineering Hulk).
Q: Is the gap the same for every branch?
No — it's widest in CSE and narrowest in Civil Engineering, based on the 2024 Round 5 data (Engineering Hulk).
Q: Can I switch branches after joining IIT Roorkee if I don't get my first choice?
Roorkee is one of the IITs that still allows a first-semester branch-change option for top-performing students, though the criteria are strict (Wikipedia).
Q: Does IIT Bombay allow branch changes?
No — IIT Bombay has abolished branch-change, along with IIT Hyderabad and IIT Kharagpur (Wikipedia).
Q: Are reserved-category (SC/ST) cutoffs also tighter at Bombay?
Yes — for JEE Advanced 2025, Bombay's SC cutoff was rank 7–2,221 and ST was 5–1,540, versus Roorkee's SC at 28–3,872 and ST at 12–1,809 (Kollegeapply).
Q: Which institute has the higher NIRF engineering rank?
IIT Bombay — rank 3 versus IIT Roorkee's rank 6 in the 2024 NIRF engineering list (Times of India).
Q: If my rank only qualifies for Roorkee, am I settling?
Not really — Roorkee still lands inside NIRF's top 7 overall for 2025 (NIRF India), so a Roorkee seat represents a top-tier outcome even if the rank required is more forgiving than Bombay's.
