Say goodbye to Workers' size limit — deploy up to 64 MiB on every plan!
Hi everyone, it's me! Here's some quietly exciting news for anyone using Cloudflare Workers!
Cloudflare Changelog

What was announced?
According to the Cloudflare Changelog, the deployable bundle size limit for Workers has been raised to 64 MiB for both free and paid plans. Larger dependencies and heavier frameworks are now much less likely to hit a size wall.
The story so far
Previously, Cloudflare checked the size of your bundle after Wrangler compressed it, rejecting deploys over 3 MB on the Free plan or 10 MB on the Paid plan. Since the limit applied to the compressed size, it was easy to bump into as soon as your dependencies grew.
What changes
The compressed-size check has been removed entirely. Cloudflare now only checks the uncompressed size of your bundle, with a single 64 MiB limit across all plans. Heavier libraries and frameworks that you may have previously ruled out are now much easier to bring into a Worker.
Dive Deep
To check your bundle size before deploying, you can run:
wrangler deploy --outdir bundled/ --dry-run
Which gives output like this:
Total Upload: 259.61 KiB / gzip: 47.23 KiB
The "Total Upload" value is the uncompressed size that counts against the 64 MiB limit. The "gzip" value is shown for reference only — it's no longer part of the limit.
Wrap-up
- Workers' deploy size limit is now a unified 64 MiB (uncompressed) across free and paid plans
- The old limits were 3 MB (Free) and 10 MB (Paid), measured after compression
wrangler deploy --outdir bundled/ --dry-runlets you check your size ahead of time- "Total Upload" counts against the new limit; "gzip" is informational only
If Workers' size limit has been holding back your dependencies or framework choices, this update is worth trying today!
