I built a jewelry size database for women with tiny fingers in one day

The problem
If your ring size is 2, 3, or 4, most jewelry brands don’t make your size. I’m 153 cm tall with size 3 ring fingers and a 13.5 cm wrist. Standard rings start at size 5. I got tired of Googling “small ring” and finding nothing useful, so I built the database I wish existed.
What I built
A free, filterable database of 31 jewelry brands verified to carry truly small sizes.
- Filter by ring size, bracelet length, price, material, adjustable/not
- 31 brand pages with detailed size info
- 8 size‑filter pages (e.g., “all brands with ring size 2”)
- Ring size conversion chart (US/JP/EU/UK)
- Printable ring sizer tool

The Japanese brand discovery
This was the biggest surprise. Japanese jewelry brands like Agete, 4C, and Nojess carry ring sizes from US 1.5 as standard inventory – that’s three full sizes.
The reason is simple: the average ring size in Japan is US 4‑5, versus US 6‑7 in the West. So Japanese brands naturally make smaller sizes. Most people outside Japan have limited options for such sizes.
Tech stack
- Plain HTML/CSS/JS
- GitHub Pages (zero hosting cost)
- 46 pages total
- Brand data stored in a single JSON file
- 31 individual brand pages + 8 size‑filter pages auto‑generated from that JSON (programmatic SEO)
- Built the whole thing in one day with AI assistance
What’s next
- Applying to affiliate programs (ShareASale, CJ Affiliate, Etsy)
- Adding more brands (targeting 100 +)
- Monitoring if programmatic SEO still works after Google’s March 2026 core update
The repo is public:
I’d love feedback. If you know any brands that carry small ring sizes, let me know.
