Why ad copy gets truncated differently across placements

When you run a Meta ad with Advantage+ placements enabled, the same copy appears across Facebook Feed, Instagram Feed, Stories, Reels, Right Column, Messenger, and Audience Network - each with different character limits and display logic. Text that reads perfectly in one placement may be cut off mid-sentence in another.

The most common mistake advertisers make is writing primary text that only works when fully visible. If your hook or key benefit appears after the first 125 characters, mobile users never see it. This tool lets you catch those problems before you spend a dollar.

Character limits by placement

Writing copy that works across all placements

The safest strategy: write your most important hook or benefit in the first 125 characters of primary text, then continue with supporting details. Think of the first sentence as your only guaranteed impression. Write headlines that stand completely alone - they appear below the creative in a different context than the primary text, so they need to make sense without it.

For Stories and Reels, text in your primary copy field is essentially invisible. If Stories are a significant placement for you (common for fashion, beauty, food, and consumer apps), upload a separate vertical creative with your key message baked into the video or image.
