Kei te wātea te kiriata totoro i roto i ngā matotoru me ngā whānui rerekē hei whakatutuki i ngā hiahia takai me ngā momo taonga.
Ko te matotoru e whakaatuhia ana i roto i te maikorona, i te ine rānei, ko te matotoru paerewa o te kiriata totoro he 12-30 maikorona (μm) 50 ine rānei – 120 ine.
Ko te whānui kei waenga i te 12 ki te 20 inihi (30 ki te 50 henemita) ā, ka taea te whakarite kia rite ki ngā whakaritenga motuhake.
Matotoru:
Ka whakaratohia e ngā matotoru rerekē ngā taumata rerekē o te kaha me te tiaki.
He pai ngā kiriata matotoru, pērā i te 20-35 μm (80-140 ine), mō ngā mea taumaha, koi rānei, ā, ka nui ake te ātete ki te poka, arā, te kiriata e āhei ai ki te tu atu ki ngā kawenga taumaha.
He pai ngā kiriata angiangi, pērā i te 10-15 maikorona (40-90 ine), mō ngā taonga mama ake, mō ngā wā rānei e aro nui ana ki te whai hua.
Whānui:
He rerekē te whānui o te kiriata totoro, mai i te 12 inihi (30 cm) ki te 20 inihi (50 cm).
Ko te whānuitanga o te rauemi e whakawhirinaki ana ki te rahi me ngā āhuatanga o ngā taonga e takaihia ana.
Kōwhiria he whānui ake ina tākai ana i ngā taonga nunui, matotoru rānei, kia pai ake ai te taupoki me te pumau.
Me pēhea te tatau i ngā whakaritenga mō te kiriata totoro e hiahiatia ana
| Tātaitanga Taumaha | Tātaitanga Roa |
| Taumaha = Roa (m) * matotoru (um) * whānui (cm) * 0.918 | Roa = Taumaha (kg) / matotoru (um) / whānui (cm) / 0.918 |
| Homai he Tauira: | |
| 550m te roa, 22um te matotoru, 50CM te whānui, tata ki te 5.5 kg te taumaha. (550*0.022*0.5*0.918=5.5) | |
| Taumaha 3 kirokaramu, matotoru 22um, whānui 50CM, roa tata ki te 297m. (3/0.022/0.5/0.918=297) | |
