How to Check Paragraph Length in an Email (How Many Lines on a Phone)
To check paragraph length in an email, count the sentences in each paragraph and the lines it takes at a phone-width screen. The email paragraph length checker does it: paste the email with a blank line between paragraphs, set the width and your limits, and flagged paragraphs say which limit they passed.
The by-hand way
- Send the email to your own phone, or narrow your window.
- Look at the shape. A paragraph that fills the screen is the one to break.
- Count its sentences and lines.
This works for one email. For a template library, a table beats eyeballing.
Step 1: paste the email
Paste the text with a blank line between paragraphs. Every paragraph is listed with its sentences, words and wrapped lines.
Step 2: set the width and the limits
Set the characters on one line to picture the screen, and your limits for sentences and lines. The width starts at 40 to picture a narrow phone and can be 20 to 120. The limits start at 3 sentences and 4 lines. Nothing checks them for you and the tool gives no score.
Step 3: read the table
| Column | What it shows |
|---|---|
| Sentences | How many in the paragraph |
| Words | The word count |
| Lines | How many lines at your width |
| Flag | Which limit it passed |
The tool wraps the words the way a screen would. A word longer than the width takes lines of its own. Real fonts and apps wrap differently, so use the number to compare paragraphs: the one that takes seven lines when the rest take two is the one to break. A paragraph of one sentence is counted in the one-sentence figure, because a run of them can read as a list.
Step 4: break and paste again
Break the flagged paragraphs in your own words and paste the email in again. Paragraphs hold sentences, so also use the email sentence length checker. For a plain-text copy of an HTML email, use HTML to plain text, and for the picture-to-text balance, the email image to text ratio checker. See also cold email templates.
What this check cannot do
- Lines are a simple wrap, not how any one app or font shows the email.
- It reads plain text. HTML and images are not looked at.
- One 60-word sentence is one sentence; check sentences separately.
- It does not judge whether a short paragraph reads well.
Before you send, verify the list
Before you send, verify the list at the verify page: the first 100 email checks are free with a Google sign-in, no card. Each address comes back valid, risky or invalid with a reason, and nothing is sent to anyone on the list. A well-edited email still bounces if the address is dead. For larger or recurring lists, see bulk email verification, list cleaning and pricing.

Common questions
How do I check paragraph length in an email?
Count the sentences in each paragraph and the lines it takes at a narrow width. A paragraph length checker does this and flags the ones over your limits.
How long should an email paragraph be?
No mailbox provider publishes a limit. The tool starts at 3 sentences and 4 lines, common choices for cold email, and you can change both.
How are lines counted?
Words wrap at the width you set, from 20 to 120 characters, starting at 40 to picture a narrow phone. It is a picture, not a measurement of any one app.
Are greetings flagged?
They count as paragraphs but are never flagged, as they are short.
Does it check HTML emails?
It reads plain text. HTML and images are not looked at.
Check your list before you send
Real mailbox checks over SMTP, and nothing is sent to the address. Sign in with Google and your first 100 email checks are free, no card. Plans for bigger lists are on the pricing page.
