Fix line spacing around a logo in an Outlook signature

Unwanted gaps around a logo in an Outlook signature usually come from one of three sources. The first is paragraph formatting: spacing before or after a paragraph, a line-spacing multiple, or a hard return where a soft line break was intended. The second is image placement: an image placed in line with text makes its line as tall as the image. The third is the image file: transparent or white padding around the exported logo shows up as blank space. Each cause has a quick check, so confirm which one applies before changing anything.

No screenshots, Outlook version details or logo files were supplied with this question. The causes below are therefore possible causes, not confirmed ones. Each is paired with a check that confirms or rules it out.

What the signature actually contains

A logo in an Outlook signature is almost always a raster image, usually a PNG or JPG exported from the logo artwork. It is not the vector artwork itself. Support for SVG in email signatures varies across Outlook versions and across the mail clients your recipients use, so a raster export is the usual choice. The vector source still matters, because it is where you control the export bounds, and those bounds decide how much empty canvas travels with the image.

If you are working from a file labeled SVG, EPS, AI or PDF, open it and confirm it contains editable paths before relying on it. The extension alone does not guarantee this. Some files with vector extensions only wrap an embedded raster image, and trimming the bounds of such a file will not behave like editing true vector artwork.

Symptoms, likely causes and checks

Symptom | Possible cause | Check | Fix

Gap above or below the logo that does not change when you adjust text spacing | Empty canvas around the logo in the image file | Click the logo; the selection box extends past the visible artwork | Re-export with bounds fitted to the artwork

Gap between every line, not only around the logo | Paragraph spacing or hard returns between lines | Turn on formatting marks; a ¶ ends each line | Set spacing before and after to 0, line spacing to Single, and use Shift+Enter between lines

The text line beside the logo is much taller than the others | Logo sits inline with text, so the line takes the image height | The text aligns to the bottom of the logo | Put the logo on its own line or in a separate table cell

Spacing looks fine in your compose window but wrong for recipients | Template table padding, or a different rendering engine on the recipient's side | Send tests to more than one mail client and compare | Set cell padding and margins explicitly and simplify the layout

Logo and gaps appear larger on some screens | Image displayed at its pixel size instead of a set display size | Compare the same message on displays with different scaling | Set explicit width and height for the image

Check the image bounds first

This is the fastest check. Click the logo in the signature editor or in a draft message. If the selection handles sit well outside the visible logo, the extra space is part of the image itself. No paragraph setting will remove it.

To fix it, go back to the source artwork and export again. Fit the artboard or export area to the artwork bounds, or use an option that exports only the selected artwork. Then replace the image in the signature. Viewing the exported PNG over a checkerboard or dark background makes leftover transparent padding easy to see.

Some brand guidelines define a clear-space zone around a logo. Trimming empty export canvas does not change the mark itself, and you can recreate clear space with cell padding in the signature layout. If the logo belongs to someone else, permission to download the file does not cover cropping, recoloring or redrawing the mark. Check the owner's usage guidelines before you go beyond trimming empty canvas.

Check paragraph formatting

In classic Outlook for Windows, the compose window uses a Word-based editor. Pressing Enter starts a new paragraph, which carries its own spacing before and after. Pressing Shift+Enter inserts a line break inside the same paragraph, so no paragraph spacing is added. A signature built with Enter between every line often looks loosely spaced, especially next to a logo.

The signature editor offers limited formatting tools, so it is often easier to work in a draft. Follow these steps:

• Open a new message and insert the signature.
• Turn on formatting marks with the ¶ button on the Format Text tab. This shows where paragraphs end.
• Select the signature, open the Paragraph settings, set spacing before and after to 0 and line spacing to Single.
• Replace hard returns between lines with Shift+Enter where you want lines to sit tightly together.
• Copy the corrected signature back into the signature editor and save it.

The newer Outlook and Outlook on the web use a different editor, and their formatting options are not the same. The Enter versus Shift+Enter distinction usually still applies there.

Check how the logo sits in the line

An inline image behaves like a very tall character. The line it sits on grows to fit it, and text on that line aligns to the image's bottom edge. If your name or title shares a line with the logo, that line will look stretched.

The steadier layout is a two-column table with the logo in one cell and the text lines in the other. Set the cell padding to zero, or to the clear space you want, and remove any empty rows or cells. If the signature came from an HTML template or was pasted from a designer's file, look for hidden padding, empty paragraphs inside cells, and spacer images. These often cause the gaps.

Editing the signature HTML directly

Classic Outlook for Windows stores signatures as files in the user's Signatures folder, usually found under %APPDATA%\Microsoft\Signatures. Advanced users can set spacing explicitly in the HTML version of the signature. Back up the file first. Outlook may rewrite the file if you later open and save that signature in the built-in editor, which can undo manual changes. The snippet below illustrates the approach. Replace the file name and dimensions with your own values.

<table cellpadding="0" cellspacing="0" border="0">
  <tr>
    <td style="padding:0 12px 0 0; vertical-align:top;">
      <img src="logo.png" width="[display width]" height="[display height]"
           style="display:block; border:0;" alt="[Company name] logo">
    </td>
    <td style="vertical-align:top;">
      <p style="margin:0; line-height:[value]; mso-line-height-rule:exactly;">Name<br>Title<br>Phone</p>
    </td>
  </tr>
</table>

In this snippet, display:block on the image removes the small gap that inline images can leave below them. Zero paragraph margins remove paragraph spacing. The mso-line-height-rule property tells Outlook's Word-based rendering to apply the stated line height exactly.

Image size and display scaling

If the logo has no set display size, some Outlook setups show it at its pixel dimensions or scale it with the display. A high-resolution export can then show up oversized and push surrounding lines apart. A common approach is to export the logo at a multiple of its intended display size for sharpness, then set the display width and height explicitly. Confirm the result by viewing the same message on displays with different scaling settings.

Verify the fix

• Send a new message to yourself, then reply to it. Outlook may use a different signature for replies, so check both.
• Open the test in at least one other mail client, such as webmail or a phone app, and compare the spacing.
• Click the logo again and confirm the selection box now fits the visible artwork.
• With formatting marks on, confirm the signature lines end where you intend and no stray empty paragraphs remain.

If the gap persists after the image bounds, paragraph spacing and layout all check out, the remaining cause is likely specific to your Outlook version or your recipient's client. Pinning it down would require details that were not supplied here: the exact version, a screenshot, and how the signature was built.
