Clothing and shoe sizes: across systems
Shopping across borders turns every purchase into a guessing game: an Italian size 42 is a European 38, a US 6, and a UK 10, while the same number maps differently for shoes and men. An international size converter maps clothing and footwear across Italian, European, US, UK, and Japanese systems using industry sizing charts, eliminating the expensive return trips.
TL;DR
- Apparel sizes are based on body measurements in centimeters or inches, but each region names them differently: Italian sizes run about 4 numbers above European sizes, and US women sizes run about 32 numbers below European sizes (EU 38 = US 6)
- Sizing Maps & Systems: Italian Size = European Size + 4 | Shoe sizes map through foot length (cm / Pa
- Example 1: Converting a women Italian apparel size 42
How it works
Apparel sizes are based on body measurements in centimeters or inches, but each region names them differently: Italian sizes run about 4 numbers above European sizes, and US women sizes run about 32 numbers below European sizes (EU 38 = US 6). Shoes use separate conversion tables based on foot length in centimeters (Paris points in Europe, inches in the US).
The math
Convert the known size to the underlying measurement (foot length or body dimension), then map that measurement into the target system using the standard conversion tables for the gender and garment type.
For apparel, Italian sizes are typically 4 numbers higher than European sizes (IT 42 = EU 38 = US 6 for women). Shoe conversions use per-system tables: IT 42 men ≈ US 9 ≈ UK 8.5 ≈ JP 27 cm.
Examples
Example 1: Converting a women Italian apparel size 42
- Italian size: 42
- European equivalent: 42 - 4 = 38
- US equivalent: 42 - 36 = 6
- UK equivalent: 42 - 32 = 10
Example 2: Converting a men shoe size IT 42
- Italian shoe size: 42
- US size: 9
- UK size: 8.5
- Japanese size: 27 cm foot length
Real-World Uses of a Size Converter
✦ Cross-Border Online Shopping
Shoppers buy from international stores with confidence by converting their home size into the seller system before ordering.
✦ Gift Buying
Buying clothes or shoes as gifts without the recipient measuring themselves becomes feasible using their known size in any system.
⚠ Common Size Conversion Mistakes
- Ignoring Manufacturer Variance: Sizing varies significantly between brands; always check the specific brand measurement guide before ordering.
- Mixing Men and Women US Sizes: US sizes differ between genders (EU 40 is Men US 7 but Women US 9).
- Forgetting Half Sizes: Some systems include half sizes while others do not, which shifts the closest match by one step.
Frequently Asked Questions About Size Conversion (6)
Is UK sizing different from US?
Yes, but the direction depends on the category: for women's clothing UK sizes run about 4 numbers above US sizes (US 6 = UK 10), while for footwear UK runs about one size below US (US 9 = UK 8.5).
What is JP sizing based on?
Japanese shoe sizing directly measures the foot length in centimeters, which makes it the most intuitive system.
Is my data kept private when I use these everyday tools?
Yes. Whether it's a word count or a time-between-dates check, nothing is sent to a server. The page does the counting locally — you can paste a draft, get 1,242 words and 6 min reading time, and close it without a trace.
Do I need internet after the first load?
Not really. Once cached, word-counter, hours, fuel-cost and the rest work offline. Handy if you're drafting on a train or counting hours on site without signal — load once, use anywhere.
How reliable are the results for work?
They follow documented rules — reading time at 200-250 wpm, hours as decimal, etc. — and are tested automatically. For casual use they're spot-on; for payroll with overtime rules or legal word-count filings, do a final check against your HR or editorial guide.
What's the fastest way to share a result?
'Share Link' does it. It encodes your inputs in the address bar, so the other person sees the exact same hours (e.g. 09:15 to 17:45 = 8h 30m) without you retyping.
