Bandwidth by plan
Bandwidth is set per site and depends on its Site plan. [2] Allowances from the pricing page: [1]
| Site plan | Monthly bandwidth | Price, yearly / monthly billing |
|---|---|---|
| Starter (free, webflow.io only) | 1 GB | $0 |
| Basic | 10 GB | $15 / $25 a month |
| Premium | 50 GB included; add-ons up to 2.5 TB total | $25 / $39 a month plus add-ons |
| Ecommerce Standard | 50 GB | $29 / $42 a month |
| Ecommerce Plus | 100 GB | $74 / $84 a month |
| Ecommerce Advanced | 100 GB | $212 / $235 a month |
What counts toward the limit
Webflow counts every byte its CDN delivers for your site: HTML, CSS, JavaScript, images, videos, fonts and files. Traffic from any user agent counts, bots included, and so do responses with any status code, including 404s and redirects. Traffic proxied through Google Tag Gateway does not count. [2]
Scripts and content loaded from third-party services, such as analytics or embedded social widgets, generally do not count, though they can slow pages down. Interactions usually do not add bandwidth unless they load more assets, as infinite scroll does. Deleted CMS assets can keep using bandwidth if cached pages or external links still request them. [2]
What happens when you go over
Basic and Premium sites, and legacy CMS and Business sites, get surge protection. In the first billing month over the limit, Webflow notifies you by email and dashboard banner and does not charge for the overage. If usage returns to normal the next month, nothing happens and surge protection resets. [2] [3]
If you exceed the limit for a second consecutive billing month, the site plan or bandwidth add-on is automatically upgraded at the start of the next billing month, with new charges. The upgrade is sized on the lower usage of the two months. On annual billing the billing cycle stays the same and the new charge is prorated. Webflow says it cannot refund bandwidth overages, but you can downgrade if usage later drops. [3] [4]
Annual subscribers are still measured monthly: the billing month starts on the subscription date, so a plan started March 5 runs March 5 to April 4, then April 5 to May 4. [3]
Estimate your monthly usage
A planning estimate: monthly bandwidth is roughly average page weight multiply by monthly page views, plus a margin for bots and error pages, which Webflow counts. Repeat visitors whose browsers cache files can bring the real figure lower, so treat this as an upper-bound check. Webflow's own pricing note says 50 GB usually covers 5,000 to 25,000 page views. [1] [2]
Hypothetical figures below; 1 GB is treated as 1,000 MB.
| Scenario | Calculation | Monthly estimate | Plan fit |
|---|---|---|---|
| Brochure site, unoptimized photos | 1.5 MB x 8,000 page views | 12 GB | Over Basic's 10 GB |
| Same site after compression | 0.8 MB x 8,000 page views | 6.4 GB | Fits Basic |
| Image-heavy portfolio | 3 MB x 30,000 page views | 90 GB | Premium plus a +50 GB add-on |
| Premium with +50 GB add-on | $25 + $20 a month, yearly billing | $45 a month | $69 a month on monthly billing |
Premium bandwidth add-on prices
Selected add-on tiers from the pricing page, on top of Premium's plan price. [1]
| Add-on | Yearly billing | Monthly billing |
|---|---|---|
| +50 GB | $20/mo | $30/mo |
| +100 GB | $40/mo | $60/mo |
| +150 GB | $60/mo | $90/mo |
| +250 GB | $100/mo | $150/mo |
| +450 GB | $174/mo | $260/mo |
| +950 GB | $374/mo | $560/mo |
| +2.45 TB | $974/mo | $1,460/mo |
Optimization checklist before you pay more
Start in Site settings, Site usage, which shows total bandwidth, a breakdown by file type and the top assets. Webflow flags assets that meet its optimization criteria. [2]
- Resize images over 2,000 px on either side to their display size.
- Convert images that are not WebP or AVIF using the Assets panel Compress action.
- Replace GIFs over 1 MB with MP4 video set to autoplay, loop and muted.
- Embed self-hosted videos over 100 MB from YouTube or Vimeo, or upload a lower-bitrate file.
- Trim font files over 80 KB that load more than 1,000 times by removing unused weights and styles.
- Move JavaScript or CSS bundles over 250 KB from site-wide custom code to the pages that use them.
- Replace background images with inline images positioned with object-fit, since responsive images are not generated for background images.
- Delete unused assets, fonts, styles and interactions, and use robots.txt to keep unwanted bots off heavy pages.
Questions before you decide
Will Webflow take my site offline if I exceed bandwidth?
Webflow's help center describes notifications and, after a second consecutive month over the limit, an automatic plan or add-on upgrade with new charges. It does not describe taking the site offline.
Do bots count toward Webflow bandwidth?
Yes. Webflow counts traffic from any user agent, bot or not, and responses with any status code. The usage dashboard does not separate bot traffic.
Can I get a refund after an automatic bandwidth upgrade?
Webflow says it cannot refund bandwidth overages, but you can downgrade if usage falls below the new plan limits in later months.
