Reading the Bible Calculator: How Long Does It Actually Take to Read or Study the Bible?

“I should really read the whole Bible” is one of those intentions that a lot of people carry around for years without ever quite starting, not because they don’t want to, but because the size of the task is vague enough to feel intimidating. Sixty-six books. Over a thousand chapters. Is that a six-week project or a six-year one? Most people genuinely don’t know, and that uncertainty is often enough to keep the whole thing permanently on the “someday” list.

The answer turns out to be entirely knowable. The Bible runs to a specific number of words, somewhere around 783,000 in most English translations, and reading speed is a measurable thing. Once you know your own pace and how much time you can realistically set aside, “how long would this take” stops being a vague worry and becomes a number you can actually plan around.

This calculator does that working out. It uses real word counts for every one of the 66 books, not rough estimates, and lets you set your own reading speed, how much study or note-taking time you want to add, and how many minutes a day you can give it. It also shows every single book broken down individually, so “how long does Psalms take” or “how short is Jude really” has an actual answer rather than a guess.

Who Is This Calculator For?

This is built to be useful regardless of why someone wants the number, there’s no assumption here about belief or motivation. It’s for:

• Anyone planning to read the Bible for the first time and wanting a realistic sense of the commitment before starting, rather than discovering halfway through that the pace they picked isn’t sustainable.
• People restarting after a previous attempt stalled, often because the original plan (a chapter a day, say) didn’t account for how much longer some chapters are than others, leading to frustration when Psalm 119 takes five times as long as the day before.
• Students and researchers who need to budget time for reading specific books or sections as part of academic or comparative religious study, without any devotional framing required.
• Anyone curious about the numbers, how long is Genesis really, which book is the shortest, how does reading compare to listening, independent of any reading plan at all.
• People deciding between reading and listening and wanting an actual time comparison between the two rather than a guess.

What This Calculator Is (and Isn’t)

• It’s purely practical. No theology, no commentary on meaning, no suggestion about which translation or approach is best. Just word counts, reading speed, and time.
• It’s not a substitute for an actual reading plan app if you want daily reminders, scheduled readings, or community accountability, there are dedicated apps for that. What this gives you is the underlying maths so you can build or choose a plan that’s realistic for your pace, rather than picking one blind.

How to Use the Reading the Bible Calculator

Start by choosing your scope: the full Bible, Old Testament only, New Testament only, or just the Gospels. This sets the headline totals in the summary and hero sections, though the book-by-book table below always shows all 66 books regardless, so you can look up any individual book at any time.

Next, set your reading speed. Most adults read somewhere between 150 and 250 words per minute for continuous prose, with 200 being a reasonable average. There are quick preset buttons, or you can fine-tune with the slider if you know your pace more precisely, timing yourself reading a page for a minute is a quick way to find out.

If you want to compare reading to listening, the audio Bible toggle adds a second figure based on a typical narration pace of around 130 words per minute, generally a bit slower than average silent reading speed, since narrators pace for clarity and dramatic effect rather than raw speed.

The study and note-taking sliders are both set to zero by default, giving you pure reading time. If you want to factor in pausing to reflect, cross-reference, or take notes, set a number of minutes per chapter, even a modest 2-3 minutes per chapter adds up meaningfully across over a thousand chapters.

Finally, set how many minutes a day (or week) you can realistically commit, and the calculator works out how many days the whole thing would take at that pace.

How Long Is the Bible, Really?

In most English translations, the Bible comes in at somewhere around 783,000 words across 1,189 chapters in 66 books. For context, that’s roughly the length of about eight or nine typical novels put together, or somewhere in the region of three extended fantasy trilogies.

At an average reading speed of 200 words per minute, reading every word takes approximately 65 hours. That’s a real number, but it’s worth sitting with for a moment: 65 hours spread across a year is about 11 minutes a day. Spread across six months, it’s about 22 minutes a day. Spread across 90 days, it’s around 43 minutes a day, which is why 90-day reading plans tend to ask for a noticeably bigger daily commitment than year-long ones.

None of this is a small undertaking, but it’s also not the multi-year project that the sheer size of the book sometimes implies. The total time is comparable to watching a single prestige TV series in full, substantial, but very achievable with a regular daily habit.

Why Some Chapters Take Five Times Longer Than Others

This is the single biggest reason “a chapter a day” reading plans frustrate people, and it’s almost never explained anywhere.

Chapters in the Bible were divided centuries after the original texts were written, for reference purposes, not for consistent length. Psalm 119, the longest chapter in the Bible, runs to roughly 2,500 words, which at 200 words per minute takes around 12-13 minutes to read. Psalm 117, just two chapters later, is the shortest chapter in the entire Bible at about 30 words, taking well under a minute.

This means a daily plan based purely on “one chapter” can feel wildly inconsistent, some days are a couple of minutes, others are fifteen or more. This calculator works in actual word counts rather than chapter counts for this exact reason, which is why the time-per-chapter figure in the summary is an average rather than a fixed daily expectation. If you’re building your own plan, it’s worth knowing this going in, so a longer-than-usual day doesn’t feel like falling behind.

Reading vs Studying: Two Very Different Time Commitments

“Reading the Bible” and “studying the Bible” are often used interchangeably, but the time difference between them can be substantial, and conflating the two is another common reason plans don’t stick.

Reading, in the sense this calculator measures by default, is moving through the text at a normal reading pace: taking it in, but not stopping to cross-reference, look up historical context, or write anything down. This is the fastest way through the material and the right approach if the goal is familiarity with the whole text.

Studying adds a layer on top: pausing to reflect, checking cross-references, perhaps consulting a commentary, working through the meaning of a passage rather than just its words. Even a light study pace of 2-3 minutes per chapter adds dozens of hours across the full Bible; a deeper study pace of 5-10 minutes per chapter can more than double or triple the total time commitment.

Neither approach is “correct”, they serve different purposes. The calculator lets you set the study slider to zero for pure reading, or dial it up to see what a more reflective pace would actually cost in time, which is useful for setting realistic expectations before starting either kind of plan.

Reading vs Listening: What the Time Difference Actually Looks Like

Audio Bibles have become a genuinely popular way to engage with the text: useful for commutes, chores, exercise, or simply as an alternative to reading from a page or screen. The natural question is whether listening takes more or less time than reading.

Most audio Bible narrations run at a pace of roughly 130 words per minute: measured, clear, and paced for listening comprehension rather than speed. This is generally slower than typical adult silent reading speed (150-250 wpm), which means for most people, listening to the whole Bible takes somewhat longer in total minutes than reading the same text silently, though it has the practical advantage of being something you can do while doing something else entirely, which often makes it the more realistic option in terms of actually getting through it.

For someone with a slower reading speed, around 150 words per minute, listening at 130 wpm is fairly close to the same total time, in which case the choice comes down entirely to preference and what fits into a daily routine, rather than which is faster.

The Books That Surprise People

Looking at the full breakdown by book tends to produce a few genuine surprises:

Psalms is the longest book by word count in the entire Bible: longer than Genesis, despite Genesis having far more narrative content that people associate with “long” books. At around 43,700 words across 150 chapters, reading Psalms alone at 200 wpm takes close to 3.5 hours.

Jeremiah is actually slightly longer than Isaiah in total word count, despite Isaiah generally having the higher profile, both sit in the 37,000-43,000 word range, each taking upwards of three hours to read.

Obadiah is the shortest book in the Old Testament at just one chapter and around 670 words, readable in well under five minutes. 3 John holds the title for the New Testament’s shortest book at around 219 words, finishable in roughly a minute and a half.

The four Gospels combined come to around 83,000 words, slightly more than the whole of Genesis and Exodus put together, despite generally being thought of as a quicker, more accessible read. At 200 wpm, the full Gospels take just under seven hours.

The full table in the calculator above lets you check any specific book, with the search box making it quick to jump straight to whichever one you’re curious about.

Building a Realistic Reading Plan

The most common reason reading plans fail isn’t lack of motivation, it’s an unrealistic daily target set at the start, often based on a round number like “a chapter a day” rather than an actual time calculation.

A genuinely sustainable approach: work out the total time for your chosen scope using this calculator, decide how many months or years feels realistic for you, then divide to get an actual daily minute target. Ten minutes a day, every day, for a year is around 61 hours, comfortably enough to read the whole Bible at an average pace with some time to spare for the occasional missed day.

For the New Testament alone, which comes to roughly 20 hours of reading at 200 wpm, even a modest 10 minutes a day finishes it in around four months, a genuinely achievable target for most people, and a sensible starting point if the full Bible feels too large a commitment to begin with.

The key principle that tends to actually work: consistency beats intensity. A steady 10-15 minutes daily reliably outperforms sporadic hour-long sessions, both because it’s easier to maintain as a habit and because the total time required is exactly the same either way, there’s no advantage to reading in large chunks beyond personal preference.

Frequently Asked Questions

How long does it take to read the whole Bible?

At an average reading speed of 200 words per minute, reading the entire Bible takes approximately 65-70 hours. Spread across a year, that’s around 11 minutes a day; across six months, about 22 minutes a day; across 90 days, around 43 minutes a day. The exact figure depends on your personal reading speed, which is why this calculator lets you set your own.

How long does it take to read the New Testament?

At 200 words per minute, the New Testament: roughly 181,000 words across 260 chapters, takes approximately 15 hours to read. At a steady 10 minutes a day, that’s achievable in around three to four months.

What is the longest book in the Bible?

By word count, Psalms is the longest book in the Bible at approximately 43,700 words across 150 chapters, slightly longer than Jeremiah and Genesis, which follow close behind. By chapter count alone, Psalms is also the longest with 150 chapters, far more than any other book.

What is the shortest book in the Bible?

3 John is the shortest book in the New Testament at around 219 words. In the Old Testament, Obadiah is the shortest at one chapter and roughly 670 words. Both can be read comfortably in under five minutes.

Is it faster to listen to an audio Bible or read it yourself?

It depends on your own reading speed. Most audio Bible narrations run at around 130 words per minute, which is slower than typical adult silent reading speed of 150-250 words per minute. For most readers, reading silently is somewhat faster in total time than listening, though listening has the advantage of being possible alongside other activities like driving or exercise.

How long would it take to read a chapter of the Bible per day?

This varies enormously because chapter lengths are inconsistent, some are under a minute, others (like Psalm 119) take over ten minutes. On average across the whole Bible, a chapter takes around 3-4 minutes at a typical reading speed, but a true “chapter a day” plan will have some very short days and some noticeably longer ones.

How much time should I add for studying versus just reading?

There’s no fixed answer, but a light study pace (brief reflection, perhaps a cross-reference) of around 2-3 minutes per chapter is a common starting point, while deeper study involving commentary or detailed analysis can run 5-10 minutes or more per chapter. Across the full Bible’s 1,189 chapters, even a modest study pace adds dozens of hours on top of reading time, so it’s worth factoring in before committing to a timeline.

Who built this calculator?

The Savzz Reading the Bible Calculator was built by the team at Savzz.co.uk, a UK discount code and money-saving site better known for helping people save money, but we also like building genuinely useful, original tools that nobody else has quite done properly. This one uses real word counts for all 66 books rather than estimates, and is designed to be useful to anyone wanting an honest answer to “how long would this actually take,” regardless of why they’re asking. It’s completely free to use, with no sign-up needed.

Final Thoughts

The size of the Bible is one of those things that feels much bigger in the abstract than it turns out to be in practice, 65 hours is a real commitment, but it’s also just a steady habit away rather than some impossible undertaking. Once the actual numbers are in front of you, the question shifts from “is this even feasible” to “what pace genuinely fits my week,” which is a much easier problem to solve.

Whether you’re aiming for the full text, just the New Testament, or simply want to know how long Psalms would take on a lunch break, the calculator above gives you a real answer rather than a guess, so use it to set a target you can actually stick to, rather than one that sounds good on day one and falls apart by day ten.
