A Measured Image Budget for the Web

What you will work through

• Inventory images by reader purpose.
• Measure real saved SVG bytes without inventing raster exports.
• Calculate responsive candidate coverage and identify a missing width.
• Separate local structure checks from browser, visual and network acceptance.

Contents

1. 01Start with a page and a reason for each image
2. 02Inventory the sources before making candidates
3. 03Translate display slots into candidate requirements
4. 04Choose a representation that preserves the message
5. 05Measure bytes and preserve a meaningful baseline
6. 06Treat readability and cropping as acceptance decisions
7. 07Give the layout honest dimensions and loading priorities
8. 08Write alternatives that work when the image does not
9. 09Build a release ledger someone else can reproduce
10. 10Capstone: release a measured package without invented results

Scope and limitations

• The measured fixtures are original constrained SVGs, not photographic encoding benchmarks.
• The raster ledger contains unperformed export plans, not measured compression results.
• No speed score, browser selection, visual equivalence or device result is guaranteed.
