Ukuran nuduhake jarak paling adoh antarane rong titik ing lumahing werni, minangka diukur dening rong piring podo ing kontak karo lumahing.Ukuran wiwitan yaiku diameter bola nominal, yaiku diameter bola nominal, utawa teoritis.Ukuran bal banjur ditemtokake kanthi ngukur variasi diameter bola, yaiku beda antarane ukuran diameter paling gedhe lan paling cilik.Kanggo akèh diwenehi ana variasi diameteripun kathah, kang prabédan antarane diameteripun rata-rata saka werni paling gedhe lan werni paling cilik saka akèh.
Sphericity, utawa penyimpangan saka wangun spherical, nuduhake pinten werni nyimpang saka wangun bunder sing bener (saka bunder).Iki diukur kanthi muter bal nglawan transduser linier kanthi gaya pengukur kurang saka 4 gram (0,14 oz).Grafik polar sing diasilake banjur diwatesi kanthi bunder sing paling cilik lan beda antarane bunder sing diwatesi iki lan diameter bola nominal yaiku variasi.
