Fix “Catalog feed too large” on Meta Commerce Manager
Feed file exceeds Meta's size limits. For scheduled fetches the cap is roughly 8GB compressed; for the Catalog Batch API it's per-batch limits typically around 5,000 items.
What you see in Meta Commerce Manager:
Catalog feed too large Meta's practical feed file limit is around 8GB compressed. For catalogs over 1M items, scheduled fetches become unreliable past this size.
The fix: split into multiple feeds per brand or category, or switch to incremental updates via Catalog Batch API. Smaller feeds process faster; incremental updates avoid the full-file refresh entirely.
Top causes
- 1
Catalogs over 1M items as a single file
- 2
XML feeds with verbose markup inflating file size
- 3
Large image data inadvertently included in the feed file
How to fix it
- 1
Split into multiple feeds
Per-brand or per-category feeds, each under 8GB. Meta accepts multiple feeds per catalog.
- 2
Switch to incremental updates via API
For catalogs over 1M items, full-file refreshes are inefficient. Use the Catalog Batch API for incremental updates.
- 3
Strip unnecessary content
Remove HTML, condense whitespace, drop optional fields not in use.
FAQ
How big is too big?
Practical: 5GB compressed. Theoretical max is 8GB but processing slows materially past 5GB.
