Umshini wesigqila wezicathulo. 15 cm - yisiphi isayizi sezicathulo zezingane okufanele zikhethe?

Ukukhetha izicathulo ezifanele kumntanakho kubaluleke kakhulu. Lokhu kuzokwenzela ukulungiswa kwe-gait, ukuthuthukiswa kwezinyawo, ngisho nemimoya. Eminyakeni yokuqala, izingane zikhula ngokukhulayo. Kanye nabo, ubukhulu bonyawo lushintsha. Ngakho-ke, abazali kumele bathathe umthwalo wokuthenga izicathulo nazo zonke izibopho. Futhi ezimweni ezinjalo akuyona into engavamile ukuba abazali bazibuze: uma unyawo lomntwana lingama-cm 15, yisiphi isayizi sezicathulo zezingane ezizozikhetha?

Imithetho eyisisekelo yokulinganisa ubude bonyawo

Kubazali abaningi kungaba nzima kakhulu ukucacisa ubukhulu bomlenze wengane. Amaphutha avame kakhulu:

• Abazali babuza izingane uma izicathulo zabo zithuthumela. Kodwa izingane azizweli kakhulu kule ndaba futhi zivame ukuphendula ngokungalungile. Umbono wabo ikakhulu kuxhomeke kumbala nokuma kwezicathulo.

• Ukusebenzisa umhlabathi unyawo lomntwana. Kubalulekile ukukhumbula ukuthi ubude besikhwameni buyingcosana kuneyodwa.

• Ukuzama ukubamba umunwe emkhatsini wonyawo nangemuva kwezicathulo. Kulesi simo, ingane ingakwazi ukuncibilikisa iminwe yakhe.

Phakathi nonyaka owodwa kuya ezinganeni ezintathu, ubukhulu bonyawo buyashintsha njalo phakathi kwezinyanga ezimbili kuya kwezintathu. Ngokweminyaka yobudala (kusukela kulesithathu kuya kweyisithupha), izilinganiso zithathwa njalo ezinyangeni ezine. Ezinganeni ezindala - njalo ezinyangeni eziyisithupha.

Ezinganeni ezincane, izilinganiso zenziwa nge-tape isilinganiso noma intambo, kamuva efaniswa nombusi. Ingane endala inezilinganiso ezenziwe uma imile. Linganisa ubude bemilenze emibili, njengoba amanani angase ahluke kancane. Kuyafaneleka ukuthenga izicathulo ezinombolweni enkulu noma ukuthola isilinganiso (engeza imiphumela emibili bese uhlukanisa ngesigamu).

Izindlela zokunquma ubude bonyawo nobukhulu bezicathulo ngobudala

Uma ubheka impendulo yombuzo wangaphambili (15 cm - yikuphi ukulingana kwezicathulo zezingane ezifanayo?), Ungabhekisela emazingeni. Into esemqoka ukukhumbula ukuthi zonke lezi zimiso ziphakathi futhi ziyisiqondiso, hhayi idatha ngqo. Thola usayizi ofanele uzosiza itafula lezicathulo zezingane ngokukhula. Ungayibona esithombeni esingezansi.

Sithola etafuleni ikholomu enezindinganiso ngamasentimitha bese sifuna ubude obudingekayo obuyi-15 cm. Ngusiphi isayizi sezicathulo zezingane okufanele sizikhethe? Kuvela 24-25.

Inketho yesibili ukubeka unyawo lomntwana phezu kweqabunga bese ulizungeza ngepensela. Ngokuqhubekayo eminwebeni yeminwe ibanga elivela esiphambanweni sesithupha kuya kwesithende lilinganiselwa. Lokhu kuyoba ubude bonyawo. Okulandelayo, ngokusho kwetafula, ubukhulu obufanele bukhethiwe. Isibalo ngezansi sibonisa ukuthi singakwenza kanjani lokhu.

Le ndlela ivame ukusetshenziswa emazweni ase-USSR yangaphambili. Emazweni aseYurophu, isistimu yeStechmass isetshenziswa.

Isilinganiso samaSulumane, aseYurophu naseMelika

Kunezindlela ezimbili zokunquma ubukhulu bezicathulo ezinganeni:

• I-metric, lapho izilinganiso zithathwa ngamasentimitha. Ubukhulu bonyawo buhambisana nobude bomlenze kusukela emaphethelweni eminwe esithendeni. Uhlelo olunjalo lusetshenziswa ezweni lethu.

• Stealth. Kulesi simiso, izilinganiso zenziwe kumashiya (1 max = 2/3 cm). Ngalendlela, linganisa ubude bomlenze, kodwa ubude be-insole. Isistimu enjalo isakazeke eYurophu.

E-England, zonke izilinganiso zikhonjiswe kumayunithi angaphansi kwe-Imperial: amasentimitha, izinyawo.

Kulesi sibalo esingezansi ungabona ubude bonyawo buhambisana nezindinganiso zaseYurophu, zaseMelika. Isebenzisa izinhlamvu zesayizi ezamukelwa emhlabeni wonke: amasentimitha - amayintshi, UK Usayizi - izicathulo ezivela e-UK naseScotland, US Size - USA, Australia neCanada, ama-Euro Size - abakhiqizi bezicathulo zaseYurophu.

Lapho uthenga izicathulo zezingane ezivela eYurophu, e-United Kingdom noma e-United States, udinga ukusebenzisa amatafula okuhumusha afanelekayo. Uma usenze lokhu, ungathola inani, isibonelo, konke okufanayo 15 cm. Ngusiphi isayizi sezicathulo zezingane ezizohambisana, tshela itafula.
