How Canada Sizing Actually Works
Canada follows the US band-in-inches, cup-in-letters system basically without modification, since the vast majority of stock is imported from or shared with US supply chains.
The one wrinkle: Quebec retailers sometimes list both metric and imperial on the tag, but the underlying sizing logic is still the US system underneath.
Convert Your Size
Use the calculator above to see your size across all 7 systems this site supports, Canada included. If you already know your size in another system, enter it into the Global Bra Size Converter instead of doing the math by hand.
Getting an Accurate Starting Point
Before trusting any converted size, make sure the underlying measurement is solidHow to Measure has the technique this calculator is built on, and the Sister Size Calculator is a good next step if the fit still feels wrong.
A Worked Example for Canada
Say your underbust measures 32 inches and your bust measures 36 inches. A US 32C.
Converted to Canada’s system, that becomes roughly 32″ C using the formula above. Run your own numbers through the calculator on this page rather than eyeballing the conversion. Small rounding differences near a size boundary can shift the result by a full cup letter.
Shopping Locally vs. Importing in Canada
Canadian retailers mostly stock the same sizing as their US counterparts, so cross-border online orders rarely need any extra conversion beyond what this page already covers.
Common Sizing Mistakes Shoppers Make in Canada
Canadian shoppers sometimes assume Canadian and US charts are identical in every case, when a small number of Canadian-specific labels do use their own rounding.
Another Canadian misstep is not accounting for the fact that some cross-border retailers list US sizing without noting it, leading to confusion when comparing against Canadian in-store charts.
A Note on Retail Fitting in Canada
Canadian retailers in larger cities typically offer the same fitting-room standard as their US counterparts, with similar return policies for online orders.
Ordering From the US vs. Local Canadian Retailers
Since Canada shares US-style sizing, cross-border ordering from American retailers is usually straightforward from a sizing standpoint. The complications that do come up are almost always about shipping cost and customs, not the size label itself.
A Market Split Between Two Conventions
Canadian retail carries both US-style and, less commonly, UK-influenced stock depending on the specific retailer’s supply chain, which is part of why double-checking a size chart matters more here than in a market with one dominant convention.
Bilingual Labeling Doesn’t Mean Different Sizing
Canadian packaging often shows sizes in both English and French, but this is a language requirement, not a different sizing system. The underlying band and cup numbers are the same regardless of which language label you’re reading.
Currency Conversion Adds a Small Layer of Complexity
When ordering from US retailers, remember that currency conversion and potential customs handling are separate from sizing itself. A correctly-sized order can still come with cost surprises unrelated to fit.
