LinkedIn Ad — Message Ad Resizer

What matters

LinkedIn Ad — Message Ad dimensions at a glance

LinkedIn message ad banners at 300×250 accompany sponsored InMail messages. The small format supports the text message rather than replacing it.

Message ads have high open rates on LinkedIn. The banner image supports the message text, adding visual credibility and brand recognition.

Missing or low-quality banners make the InMail feel less legitimate. Cluttered designs compete with the message text rather than supporting it.

Best practices

Use the crop intentionally

• Keep it simple — brand logo and one visual concept.
• The banner supports the message text, not the other way around.
• Use the same visual language as your other LinkedIn ad creative.
