Gupima no gushiraho urugi rwerekana imibu ubwawe nubukungu kandi byoroshye. Nubwo gupima ibipimo bisa nkaho byoroshye, bisaba umutegetsi gusa gupima ubugari n'uburebure, abantu benshi bakunze gukora amakosa mugihe babikora, biganisha kubibazo byo kwishyiriraho no kubuza imibu kwinjira. Ariko, iyo umaze kumenya uburyo bukwiye, gupima ibipimo nyabyo byumuryango w imibu ntabwo bigoye.
Iyo upimye urugi rwerekana imibu, intambwe yambere nukumenya niba ecran izashyirwa imbere cyangwa hanze yumuryango wumutekano. Guhitamo biroroshye; reba gusa icyerekezo cyumuryango wawe wakinguye. Niba umuryango wumutekano ufunguye imbere, ecran yumubu igomba gushyirwaho hanze; muburyo butandukanye, niba umuryango wumutekano ufunguye hanze, ecran igomba gushyirwaho imbere. Ibipimo nyabyo ni ngombwa mugihe ushyiraho inzugi zerekana imibu. Ibipimo byose bigomba kuba bifite uburebure bwa milimetero kugirango hamenyekane neza, birinda imibu neza bitagize ingaruka kumikorere isanzwe yumuryango.
