the best pomodoro intervals for writing sessions

July 19, 2026 · 5 min read · by focus cave

what's up with the pomodoro technique, anyway?

before we dive into timings, let's quickly recap what we're talking about. the pomodoro technique was invented by Francesco Cirillo in the late 1980s. he used a tomato-shaped kitchen timer, hence 'pomodoro,' the Italian word for tomato. the basic idea is simple: pick a task, set a timer for 25 minutes, work intensely, then take a 5-minute break. after four 'pomodoros,' you take a longer break, typically 15-30 minutes.

it's a method designed to combat procrastination and improve focus by creating a sense of urgency and providing regular relief. for many, it's a solid launchpad for getting things done, but it's more of a suggestion than a strict rulebook.

why writing feels like wrestling an octopus (especially for ADHD brains)

writing isn't just about putting words down. it's about organizing thoughts, battling the blank page, researching, editing, and trying to keep a coherent narrative. that's a lot of executive function all at once.

for brains that might be wired a little differently, like those with ADHD, the sustained attention required can feel like an uphill battle. distractions are everywhere, novelty calls, and the dopamine hit of 'finished' is still a long way off. starting is hard, and staying on track is harder. it's why so many of us look for external structures to help, and why a simple timer can sometimes feel like a superpower.

the classic 25/5: a good starting point, but sometimes too short

the original 25 minutes of work followed by a 5-minute break is the default for a reason: it's approachable. it's not so long that it feels daunting, making it excellent for task initiation. 'i can do anything for 25 minutes,' you might tell yourself.

for quick tasks, brainstorming, or chipping away at something light, the 25/5 can be perfect. however, when it comes to writing, especially creative or complex pieces, 25 minutes might feel like just enough time to finally hit your stride before the timer yanks you away. many writers find it interrupts their flow just as they're getting warmed up, leading to frustration rather than focus. it's like trying to cook a gourmet meal in 25-minute bursts.

stretching your focus: 50/10, 45/15, and the (overhyped?) 52/17

if 25 minutes feels too short, the logical next step is to extend your work blocks. many people successfully use 50 minutes of work followed by a 10-minute break, or 45 minutes of work with a 15-minute break. these longer intervals give you more time to sink into your writing, allowing for deeper concentration and less interruption to your train of thought.

you might have also heard of the '52/17 rule.' this comes from a DeskTime study in 2014, which supposedly found that the most productive employees worked for 52 minutes and then took a 17-minute break. it became a popular internet talking point. while it's an interesting data point, remember it was a specific study of office workers, not necessarily writers, and its 'scientific' claims often get exaggerated. it's anecdotal evidence at best, but it points to the idea that longer, focused bursts can be highly effective.

the downside to longer intervals is that they demand more sustained focus. for some, especially those with significant attention challenges, a 50-minute block might feel like an eternity. it's a balance: long enough to achieve flow, but not so long that you burn out or get hopelessly sidetracked.

tapping into ultradian rhythms: 90-minute cycles for deep work

beyond standard pomodoro variations, there's the concept of ultradian rhythms. these are natural cycles of energy and alertness our bodies go through every 90 to 120 minutes. Nathaniel Kleitman, a sleep researcher, identified these cycles as early as the 1950s.

this suggests that our brains are naturally optimized for roughly 90-minute periods of intense focus, followed by a dip where we need a break. applying this to writing, you might try a 60/15 or even 90/20 interval. this aligns well with Cal Newport's concept of 'deep work,' where you dedicate uninterrupted blocks of time to cognitively demanding tasks.

for writers, a 90-minute block can be a game-changer. it allows ample time to enter a flow state, develop complex ideas, and make significant progress without feeling rushed. the breaks are then longer and more restorative, letting your brain truly recharge. however, this approach requires significant self-discipline and an environment free from distractions. it's definitely an advanced-level pomodoro.

finding your writing rhythm: it's all about experimentation

the truth is, there's no single 'best' pomodoro interval for writing that works for everyone. your ideal timing will depend on many factors: the type of writing, your personal energy levels, how well you slept, if you're medicated (if you have ADHD), and even the time of day.

we're all built a little differently, and that's okay. the key is to experiment. try the classic 25/5 for a few days, then bump it to 45/15, then maybe even flirt with the 90-minute rhythm. pay attention to how you feel at the end of each work block. did you feel rushed? did you lose focus halfway through? did the break feel too short or too long?

consider a more flexible approach like flowtime, developed by Zoë Read-Bivens. with flowtime, you work until you feel your focus naturally waning, then take a break for as long as you need to feel refreshed. you record your work and break times, which gives you data on your own natural rhythms without the strict timer anxiety. it's like a pomodoro but with more wiggle room for your brain's unique needs. keeping a log of your sessions, perhaps with a tool that tracks your work times, can reveal patterns in your productivity. our session stats can help you see what's working.

ultimately, the best pomodoro interval for your writing isn't something you can look up. it's something you discover through honest self-observation and a willingness to try new things. listen to your brain, not just the timer.
