Words per minute is the whole argument
Narration pace for clear, watchable content sits around 140-160 words per minute for English, slower for technical material and faster for energetic short-form. A 2,000-word script is therefore roughly 13 minutes, not the five minutes most writers assume.
This single conversion prevents the most common production failure: running out of time budget halfway through a recording session.
Reading the number in reverse
Run the converter backwards to plan a strict format — a 60-second short holds roughly 140-160 words including the hook and the call to action, which leaves very little room for preamble.
The output is an estimate based on target pace. Your own delivery may run faster or slower; record one minute and count to calibrate.
每分钟字数就是全部论点
清晰、可观看的旁白节奏，英文大约每分钟 140–160 词，技术性内容更慢，节奏感强的短视频更快。因此 2000 词的脚本大约 13 分钟，而不是多数写作者以为的 5 分钟。
这一个换算就能避免最常见的制作事故：录到一半才发现时间预算不够。
反向使用这个数字
把转换器反过来用，可以为固定格式做规划——60 秒短视频大约容纳 140–160 词，包含钩子和行动号召，留给铺垫的空间非常小。
输出是按目标语速的估算。你自己的表达可能更快或更慢，录一分钟数一下字数来校准。
