Estimating reading time helps students plan homework better and avoid underestimating how long an assignment will take.

Reading time formula

Step 1: Find the total number of words

Start with the word count of the reading assignment. If the article, chapter, or passage does not show a word count, you can estimate it or paste the text into a word-count tool.

Step 2: Choose a reading speed

Reading speed depends on the student and the difficulty of the material. A simple starting point is:

• slow reading: about 100 to 150 words per minute
• average reading: about 200 to 250 words per minute
• faster reading: about 300 words per minute

Step 3: Divide the total words by the reading speed

Divide the total word count by the reading speed you want to use. That gives the estimated reading time in minutes.

Step 4: Add extra time for notes or difficult passages

If the reading includes highlighting, note-taking, re-reading, or harder vocabulary, add a little extra time. Real homework reading is often slower than casual reading.

Example 1

A student has a reading assignment with 1,200 words and reads at about 200 words per minute.

Example 2

A student has a longer assignment with 3,000 words and reads at about 150 words per minute.

Example 3

A student has 2,400 words to read and uses an average pace of 240 words per minute.

Common mistakes

• forgetting to match the reading speed to the difficulty of the text
• using a speed that is too fast for homework reading
• not adding extra time for note-taking or pauses
• guessing reading time without checking word count

Why estimating reading time helps

When students know how long reading may take, they can plan better, break work into smaller sessions, and avoid last-minute stress.

Use the calculator instead of doing it by hand

If you want the faster version, use the Reading Time Calculator on School Progress Hub. It helps you estimate reading time quickly from the total number of words.
