FAQs

What happens if a Facebook Feed video uses a 4:5 ratio on desktop?

Facebook Feed does not support the 4:5 video ratio on desktop, so the creative may not display as intended. The 1:1 ratio works across both desktop and mobile placements. Marketers should use 1:1 video when cross-device consistency is required.

Why does a Facebook Carousel ad fail without a landing page URL?

Facebook Carousel requires a landing page URL for each card, so missing URLs prevent proper configuration. Each card must include its own destination link to meet delivery requirements. Marketers must assign a valid URL to every card before publishing.

What is the card limit for Facebook Carousel ads and what happens if it is exceeded?

Facebook Carousel supports between 2 and 10 cards, and exceeding this range prevents the ad from meeting placement requirements. The system may block publishing or require adjustment before approval. Marketers must stay within the defined card range to ensure eligibility.

What does the 3 percent aspect ratio tolerance mean for Facebook Feed creatives?

Facebook Feed allows a 3 percent tolerance on aspect ratio, which permits minor variation from the defined ratios. Creatives that exceed this tolerance risk cropping or improper display. Marketers must keep ratios within this margin to maintain layout integrity.
