Blocking data quality

Fix “Catalog file too large” on Pinterest Catalog

Feed file exceeds Pinterest's size limits — typically around 1GB uncompressed or 200MB compressed. Items can't sync until file is split.

What you see in Pinterest Catalog:

Catalog file too large

Pinterest's practical feed limit is around 1GB uncompressed. Catalogs over 500K items become unreliable past this size.

Split by category or brand. Pinterest accepts multi-feed catalogs. For very large catalogs, API-based incremental updates outperform full-file refreshes.

Top causes

1
Catalogs over 500K items
2
XML feeds with verbose markup inflating size
3
Embedded image data inside the feed file

How to fix it

1

Split by category or brand

Multiple smaller feeds under one catalog. Pinterest accepts multi-feed catalogs.
2

Switch to API-based incremental updates

Catalogs over 500K items benefit from incremental updates rather than full-file refreshes.

Feed too large

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's Pinterest's exact limit?

Around 1GB uncompressed for fetched feeds. Past that, sync becomes unreliable even if technically accepted.
