Xisaabinta jaranjarada Rotary yar xisaab ka adag jaranjarada si toos ah.
Xisaabinta jaranjarada dhaw raaxadeeda waxa loo xisaabiyaa by formula ku salaysan dhererka tallaabada.
dhererka garoonka Human u dhaxeysa 60 ilaa 66 cm, celcelis ahaan - 63 cm.
sallaan raaxo u dhiganta formula ah: 2 tallaabo height + qoto-yada = 63±3 cm.
The rabitaan ugu haboon ee sallaan - laga bilaabo 30° ilaa 40°.
tallaabooyinka jaranjarada waa in ay buuxiyaan Qoto size 45 kabaha - oo aan ka yarayn 28-30 cm.
La'aanta qoto dheer magdhow kartaa talaabo qiyaas ah.
height yada waa in ay ahaataa 20-25 cm.
Waxaad ka heli sahlaansashada jaranjarada jeestay, waxaad bedeli kartaa height of madal.
Barnaamijku wuxuu soo jiidi doonaa tafateran jeestay jaranjaro u xaglo ugu weyn oo dhinacyada.
In sawiro muujiso dhinacyada guud ee jaranjarada, sixitaanka sare ee talaabooyinka on xarig ah, labada geesood oo tallaabooyinka iyo cabbir asaasi ah oo isu tallaabooyinka.
