Calculation details
How the
timing works
Read the script aloud to confirm the timing before you record.
How is runtime calculated?
Spoken word count ÷ words per minute × 60, plus the seconds you reserve without narration. The estimated range uses reading speeds 10% faster and 10% slower than your selection. Confirm the timing with a read-through.
What counts as a word?
The calculator counts each number as one word. Contractions, hyphenated words, and dotted initials stay together; “&” counts as one spoken word. With the box checked, text inside square brackets is excluded. Parentheses are included. Remove speaker labels and timecodes yourself, and spell out numbers or initials as you will say them. Presets are intended for English scripts.
Why leave time without narration?
Add time for an opening title, a demonstration, or an end card that plays without voiceover. Do not add time for music or visuals that run underneath the narration. Normal phrasing is already reflected in the selected pace.
Why are there two word limits?
The first is the most words that fit at your selected pace after subtracting reserved time. The second uses a pace 10% slower. Use the lower limit if you need to allow for a slower read.
Is my script saved or sent anywhere?
The calculator processes your text in this browser tab. It does not upload your script, save it between visits, or add you to a mailing list. Copied and downloaded summaries exclude the script unless you check the option. Printing always leaves it out. Download a summary if you want to keep your work.
