Microsoft (Bing) Ads character limits

Microsoft Advertising mirrors Google's Responsive Search Ad limits almost exactly — which is why ads import cleanly between them. Here's the table.

Microsoft Advertising (formerly Bing Ads) uses the same Responsive Search Ad structure as Google: up to 15 headlines at 30 characters and 4 descriptions at 90. Because the limits match, copy generated for Google imports into Microsoft without rewriting — a useful shortcut for cross-network campaigns.
