免费在线字数统计工具

A standard double-spaced page in Times New Roman 12pt holds about 250–300 words. A single-spaced page holds about 500–600 words. A novel averages 70,000–100,000 words.

The average adult reads at 200–250 words per minute. So 1,000 words takes about 4–5 minutes to read. The calculator shows estimated read time at 200 wpm as a default.

The tool shows both: characters with spaces and characters without spaces. Twitter/X character limits count spaces, while some publishing platforms count only non-space characters.

Keyword density is how often a term appears as a percentage of total words. Google has no official ideal, but 1–2% is a common guideline. Focus on natural writing over hitting a specific density target.

Meta title: 60 chars. Meta description: 155–160 chars. Tweet: 280 chars. LinkedIn post: 3,000 chars. Instagram caption: 2,200 chars. Google Ads headline: 30 chars per headline.
