Question

Wrangler warned that my bundle is close to the size limit. Is that limit measured compressed or uncompressed, and how big is it?

Answer key

A correct answer says

Workers have a single 64 MiB uncompressed script size limit, and Wrangler's size warnings compare the uncompressed bundle against it.

The stale answer

Worker scripts are limited to 3 MiB (free) or 10 MiB (paid) after gzip compression.

Answer

The Workers size limit applies to the **compressed (gzipped)** bundle, which is the "gzip:" figure Wrangler prints next to the raw size when you deploy. The limit is **3 MB on the Free plan** and **10 MB on the Paid plan**. There is also a separate ceiling of **64 MB uncompressed**, but you'll normally reach the compressed limit long before that one. I answered from memory without checking Cloudflare's docs, so confirm the current numbers on the Workers "Limits" page, since they have changed before.

Grade

wrong

The judge's reason: It presents the stale compressed 3 MB/10 MB limit as current, while the key says only the 64 MiB uncompressed limit applies.
