Why Is Gmail Double Spacing My Emails?

Almost always a paragraph spacing or line break issue — here’s what’s causing it and how to fix it

---

Writing an email in Gmail and finding that every time you press Enter the text jumps down two lines — or that your email arrives at the recipient looking double spaced when you sent it single spaced — is one of those formatting frustrations that feels like it should have an obvious fix but doesn’t.

The cause is almost always how Gmail handles paragraph breaks versus line breaks, combined in some cases with pasted content bringing in outside formatting.

Here’s what’s actually happening and how to control it.

The Core Reason: Enter Creates a Paragraph, Not a Line Break

This is the fundamental cause of double spacing in Gmail and understanding it fixes the problem immediately.

When you press Enter in Gmail’s compose window, Gmail creates a new paragraph — not just a new line. HTML email, which is what Gmail uses by default, treats each Enter as the end of one paragraph and the start of another. Paragraphs in HTML have spacing built into them by default — a gap between them that makes the text appear double spaced even though you only pressed Enter once.

The fix: press Shift + Enter instead of Enter when you want a simple line break without the extra paragraph spacing. Shift + Enter creates a line break (an HTML <br> tag) within the same paragraph rather than starting a new paragraph with spacing above it.

Once you switch to Shift + Enter for line breaks within a section and reserve Enter for actual new paragraphs, the double spacing disappears and your email looks the way you intended.

Pasted Content Is Bringing in Double Spacing

If the double spacing appeared after pasting text from another source — a Word document, a website, another email, Google Docs — the pasted content brought its formatting with it. Rich text from external sources carries CSS styling, font information, and spacing definitions that Gmail applies when you paste normally.

The fix is to paste without formatting. Instead of Ctrl + V, use Ctrl + Shift + V to paste as plain text. This strips all external formatting from the pasted content and applies Gmail’s own default styling instead — eliminating any double spacing, unusual fonts, or size differences that the original source had.

If you’ve already pasted with formatting and want to fix it without retyping, select the double-spaced text, then go to the formatting toolbar and click the remove formatting button — it looks like a T with a small x or eraser. This strips the pasted formatting and returns the text to Gmail’s default.

The Formatting Toolbar Is Visible and Paragraph Spacing Is Set

Gmail’s rich text compose window has a formatting toolbar — the row of formatting buttons above the compose area showing bold, italic, font size, and similar options. When this toolbar is visible and active, Gmail is composing in HTML mode and paragraph spacing applies.

Check whether your formatting toolbar shows a line spacing or paragraph spacing control. In some versions of Gmail’s compose window, there’s a line height selector in the formatting options. If this is set above 1.0 or 1.15, your emails will appear with extra spacing between lines.

Look for the paragraph spacing option in the formatting toolbar — it may be under a More Formatting Options button or indicated by lines with arrows between them. Set it to the tightest available option.

Plain Text Mode Eliminates the Issue Entirely

If you don’t need formatting in your emails — no bold, no links, no different font sizes — switching to plain text mode removes HTML formatting entirely and with it the paragraph spacing behavior that causes double spacing.

In the compose window, click the three dots in the bottom right corner of the compose toolbar. Select Plain Text Mode. In plain text mode, Enter creates a simple line break with no extra spacing — the email behaves exactly like a text file. Every Enter is one line, not a new paragraph with spacing.

The tradeoff is that plain text emails have no formatting at all — no bold, no links that display as text, no inline images. For most correspondence this is fine. For emails where formatting matters, staying in rich text and using Shift + Enter is the better solution.

A Default Signature Is Adding Space

If the double spacing only appears at the bottom of your emails, your signature may have extra blank lines built into it.

Go to Settings → See All Settings → General and scroll down to the Signature section. Look at your signature in the editor — extra blank lines between the end of your email body and the signature, or within the signature itself, can appear as double spacing when the email is sent.

Edit the signature to remove extra blank lines. In the signature editor, the same Enter versus Shift + Enter distinction applies — replace paragraph breaks with line breaks where you want tighter spacing within the signature.

The Recipient’s Email Client Is Adding Spacing

Sometimes Gmail isn’t the cause at all — the recipient’s email client adds its own spacing when rendering the email. An email that looks correctly spaced in Gmail’s sent folder and in Gmail’s preview can appear double spaced when opened in Outlook, Apple Mail, or another client that applies its own CSS styling on top of Gmail’s.

This is a genuine cross-client compatibility issue that affects HTML email broadly. Different email clients interpret and render HTML and CSS differently — there’s no universal standard for how paragraph spacing should look across all clients.

If recipients are reporting double spacing but your email looks fine in Gmail, the recipient’s email client is adding the extra spacing. Sending in plain text mode resolves this entirely since plain text has no CSS for email clients to interpret differently.

Quoted Text in Replies Appearing Double Spaced

When you reply to an email, Gmail includes the original message as quoted text below your reply. The quoted content sometimes appears with different spacing than your reply text — either because the original email used a different spacing style or because Gmail’s quoting mechanism adds breaks.

If the double spacing only appears in the quoted portion of replies and not in your actual reply text, it’s the original email’s formatting being preserved in the quote. You can delete the quoted text if you don’t need it, or leave it knowing the spacing difference is in content you didn’t write.

A Quick Fix Reference

The spacing issue and its solution depends on where it appears:

Double spacing as you type: Switch from Enter to Shift + Enter for line breaks within a section.

Double spacing after pasting: Use Ctrl + Shift + V to paste without formatting.

Double spacing throughout the whole email: Switch to Plain Text Mode via the three dots in the compose toolbar.

Double spacing in the signature: Edit the signature in Settings → General and remove extra paragraph breaks.

Double spacing only for recipients: Send in plain text or accept that cross-client rendering differences are the cause.

A Quick Checklist

• Use Shift + Enter instead of Enter for line breaks — eliminates paragraph spacing
• Paste with Ctrl + Shift + V to strip formatting from pasted content
• Use the Remove Formatting button to clear spacing from already-pasted content
• Switch to Plain Text Mode for emails where formatting isn’t needed
• Check and edit your signature for extra blank lines
• Accept cross-client rendering if recipients report spacing your Gmail preview doesn’t show

The Bottom Line

Gmail double spacing almost always comes down to the difference between Enter (new paragraph with spacing) and Shift + Enter (new line without spacing). Switching to Shift + Enter for line breaks within your email resolves it immediately and permanently — no settings change required, just a different key combination.

For double spacing caused by pasted content, Ctrl + Shift + V strips the outside formatting before it can cause problems. And for anyone who finds HTML email formatting more trouble than it’s worth, plain text mode removes the spacing behavior entirely.

Gmail isn’t adding spaces you didn’t ask for — it’s treating Enter as a new paragraph, which has spacing. Shift + Enter gives you a line break without it.
