Boy en güvenilir girdidir — yaş yaklaşık bir göstergedir. Bazı markalar küçük kalıplı (Zara, H&M) veya büyük kalıplı (Carter’s, Old Navy) olabilir; satın almadan önce yorumları ve markanın kendi tablosunu kontrol edin.
Kids' clothing sizes are confusing across multiple dimensions: age-based labels (3M, 6M, 9M, 12M, 18M, 24M, 2T, 3T, 4T, then 4, 5, 6 ... 14, 16) don't match most kids' actual sizes because children grow at vastly different rates. A child's clothing size at 3 years old can be anywhere from 2T to 5T depending on growth percentile and individual variation. Buying by labeled age leads to expensive mistakes. The reliable approach: use HEIGHT first as the primary measurement, weight as a secondary check, and age only as a rough sanity check. Brands publish height-based size charts; align purchases to those, not to your child's birthday-age.
The size guide takes age, height, and (optionally) weight, then outputs recommended size across major US retailers. Standard size progressions: newborn / 0-3M (5-8 lbs, under 23 inches), 3M (8-12 lbs, 23-25 in), 6M (12-16 lbs, 25-26.5 in), 9M (16-19 lbs, 26.5-27.5 in), 12M (19-22 lbs, 27.5-29 in), 18M (22-25 lbs, 29-31 in), 24M / 2T (25-28 lbs, 31-34 in), 3T (28-32 lbs, 34-37 in), 4T (32-37 lbs, 37-40 in), then progressing through 4/5/6/7/8/10/12/14/16 with increasing height and weight ranges.
Practical kid-clothing economics: (1) Babies grow fastest 0-12 months — don't buy ahead more than 3 months because they grow out before wearing. Most parents over-buy 0-3M and have unworn clothes. (2) After age 2, growth slows; you can buy 1 size up for end-of-season purchases. (3) Toddler sizes (2T-5T) and regular kids' sizes (4-7) overlap — confusingly. 4T is for toddlers (still in diapers, larger seat); 4 is for kids (potty-trained, slimmer). Same height, different cut. (4) Major brands run differently: Carter's tends to run large; Old Navy runs small; Gap consistent; H&M runs small (pick a size up). (5) European sizing (in cm: 86, 92, 98, 104, ..., 164) is height-based and more intuitive than US age-based labeling. When in doubt, look at cm-based EU size on a label and convert. (6) Hand-me-downs and consignment shops (Once Upon a Child, Kid-to-Kid) save 50-70% on kids' clothing — which is worth it because kids outgrow clothes quickly regardless.

Sık Sorulan Sorular
Should I size up?
Generally yes by half-to-full size, especially for end-of-season purchases. Kids grow fast, and tight-fitting clothes are uncomfortable. Exception: pajamas (US flammability standards require snug-fit unless flame-resistant — too-large pajamas are a safety risk for kids under 9). For everyday wear, slightly large is comfortable; significantly large is sloppy. Aim for 1-1.5 size up for items you want to last a season; size down for items the child needs to actually fit now (school uniforms, costumes for events).
What's the difference between 4T and 4?
Same height range but different cut. 4T (Toddler 4): wider seat for diapers, shorter inseam, fuller cut, generally for kids still in diapers or recently potty-trained. 4 (regular kids): slimmer cut, longer inseam, designed for fully potty-trained kids. Most retailers stop selling toddler sizes after 5T; regular kids sizes start at 4 (overlap is intentional — choose based on whether your child is in diapers).
How do European sizes work?
European sizing uses height in cm: 86 = 86 cm tall, 92 = 92 cm tall, etc. Standard intervals: 50, 56, 62, 68, 74, 80, 86, 92, 98, 104, 110, 116, 122, 128, 134, 140, 146, 152, 158, 164. More intuitive than age labels because it's based on actual measurement. To convert: measure child's height in cm, find the closest size up. Most European brands also include US-equivalent labels for export markets.
Why do brands fit so differently?
No standardization in kids' sizing. Same labeled “size 6” varies 1-2 inches across brands. Carter's and OshKosh tend to run generous (size down possibly). Old Navy and H&M tend to run small (size up). Gap, Children's Place are roughly true to label. Patagonia and Hanna Andersson run true to label but quality is higher. When buying a new brand, check reviews for sizing comments and start with one item to test before bulk-buying.
How fast do kids grow?
Highly variable but rough averages: birth to 12 months adds 10 inches and triples weight. 12 months to 2 years adds 4-5 inches. 2 to 5 years adds 2-3 inches per year. 5 to 10 years adds 2 inches per year. 10 to 14 years (puberty growth spurt) adds 3-4 inches per year. After 14, growth slows. So clothes for ages 0-2 last weeks; ages 5-10 may last months to a year if you size up; ages 10-14 last only a season due to growth spurts.
Are hand-me-downs OK?
Yes, and they're economically smart. Kids outgrow clothes long before wearing them out — most secondhand kids' clothing is in excellent condition. Sources: family/friend hand-me-downs (free), consignment chains (Once Upon a Child, Kid to Kid — 50-70% off retail), thrift stores (Goodwill, Salvation Army), Buy Nothing groups (free local exchange). Children's clothing depreciates fast; resale at 30-50% of retail is common. Buying secondhand kids' clothing is one of the highest-leverage household budget cuts available.
