Igipimo cyo kugabanyayerekeza ku mubare w'ibirahure byujuje ibisabwa nyuma yo gukata ikirahure mbere yo kugisukura.
Ifurumu ni ikirahure cyujuje ibisabwa gifite ingano isabwa x uburebure bw'ikirahure busabwa x ubugari bw'ikirahure busabwa / uburebure bw'urupapuro rw'ikirahure / ubugari bw'urupapuro rw'ikirahure = igipimo cyo gukata
Mbere na mbere, twagombye gusobanukirwa neza ingano y'urupapuro rw'ikirahure rusanzwe n'umubare wa milimetero (mm) zigomba gusigara ku burebure n'ubugari bw'ikirahure mu gihe cyo gukata:
| Ubunini bw'ikirahure (mm) | Ingano isanzwe y'urupapuro rw'ikirahure kibisi (mm) | Milimetero igomba gusigwa kuri L. & W. y'ikirahure (mm) |
| 0.25 | 1000×1200 | 0.1-0.3 |
| 0.4 | 1000×1500 | 0.1-0.3 |

| Umubare nyuma y'urupapuro rusanzwe rugabanyijwemo ingano y'ikirahure gikenewe | 4.02 | 18.48 | 13.86 | 5.36 |
| Umubare w'ibirahure byujuje ibisabwa byose | 4×18=72pcs | 13×5=65pcs | ||
| Igipimo cyo kugabanya | 72x454x131/1830/2440=95% | 65x454x131/1830/2440=80% | ||

Birumvikana ko twamenye ko urupapuro ruto rwa 1830x2440mm ari rwo rwa mbere rukoreshwa mu gukata.
Ese ufite igitekerezo cy'uko wabara igipimo cyo kugabanya?
