UPSC Mains prescribes approximate word limits per mark value. Treating limits as flexible "suggestions" costs time — and time lost on one question is marks lost on another.
Rule of thumb
Stay within ±10% of the prescribed word count. Over-writing 10-mark answers is the most common time-management failure.
Official word limits by marks
| Marks | Prescribed words | Time target | Typical use |
|---|---|---|---|
| 10 | 150 | 7 min | Most GS I–III questions |
| 15 | 250 | 12 min | Deeper GS themes |
| 20 | 350 | 18 min | GS IV case studies, some GS |
Why word limits exist
Examiners assume ~15 words per mark under exam conditions. Limits keep the paper completable in three hours. A candidate who writes 200 words on every 10-mark question often leaves 2–3 questions unattempted — automatic mark loss.
How to train word discipline
- Plan in margin — 4 lines max for 10 marks; if the plan does not fit, re-read the question.
- One idea per subhead — redundancy is the main cause of over-writing.
- Practice with a timer — stop at 7 minutes even if unfinished; diagnose why.
- Count once weekly — word-count one answer after writing; calibrate intuition.
Under-writing vs over-writing
| Problem | Signal | Fix |
|---|---|---|
| Over-writing | Over 180 words on 10 marks | Cut intro; merge subheads |
| Under-writing | Under 120 words on 10 marks | Add one anchor per subhead |
| Padding | Generic lines, no anchors | Replace with scheme/judgment/data |
