How long should your breaks actually be
Five minutes after each focus block, and fifteen to thirty after every fourth. Scale both with the length of the block rather than treating them as fixed.
The classic ratio is roughly one part rest to five parts work, and it holds up surprisingly well. What breaks it is applying the same five minutes to a 45 minute block as to a 25 minute one. Longer focus needs longer recovery, in about the same proportion.
A ratio worth using
- 25 minute focus, 5 minute break
- 45 minute focus, 8 to 10 minute break
- 90 minute focus, 15 to 20 minute break
- Every fourth break, roughly triple it
What a break is for
The break exists to let attention recover, which means it has to be a different kind of activity from the work. Reading a feed is the same shape as reading a document, so it does not restore anything. Standing up, looking at distance, moving and drinking water do.
When to skip the rules
If you are genuinely deep in something at the end of a block, finishing the thought is usually right. What is not right is skipping the break repeatedly, which is how a productive morning becomes an unusable afternoon. Take the long break when it arrives, especially when you feel like you do not need it.

Do not let breaks inflate the numbers
If you track focus time, count only the focus. A tool that logs break minutes alongside work minutes produces a number that flatters you and tells you nothing.
