Page weight
A heavy page is slow on a phone, costs your visitors data and consumes energy. We load your page like a first-time visitor and weigh everything that comes through.
How the grade works
It is based on the weight actually transferred: A up to 0.5 MB, B up to 1 MB, C up to 2 MB, D up to 3.5 MB, E up to 5 MB, F beyond. For comparison, the median web page is about 2.3 MB on phones (HTTP Archive, 2024).
Where to start
01
Images
Usually more than half of the weight. Right size, WebP format, and loading="lazy" for those below the fold.
02
Scripts
Every plugin adds some. Remove what you no longer use.
03
Compression
gzip or Brotli divides text files by three or four, at no cost.
Frequently asked questions
How much does my web page weigh?
The tool loads your page like a first-time visitor, with no cache, then weighs everything that comes through: scripts, styles, images and fonts. You get a grade and an estimate of the carbon footprint.
How is the grade calculated?
It is based on the weight actually transferred: A up to 0.5 MB, B up to 1 MB, C up to 2 MB, D up to 3.5 MB, E up to 5 MB and F beyond that.
Where should I start to lighten my page?
With the images, often more than half of the weight: right size, WebP format and lazy loading for those lower on the page. Then remove unneeded scripts and turn on gzip or Brotli compression.
