Hangul Sets Differently and the Grid Has to Follow
Korean text is composed of syllable blocks, each occupying a roughly square space, which gives a paragraph a very even texture and allows a line to break at almost any point. The ragged right edge that a Latin layout depends on for rhythm largely disappears, and a block of body copy becomes a solid rectangle. Headlines that needed two or three lines in English often land in one, so the vertical proportions of every hero, card and list have to be redrawn rather than inherited.
Fine typographic control differs as well. Negative letter spacing on large headings is a normal part of the local visual language, while the same treatment applied to Latin text looks cramped, so a bilingual design needs separate type rules per script rather than one shared scale. Thin weights lose legibility faster than in Latin because each block carries more strokes, and small sizes fill in. Line height has to be generous for the same reason.
Font files are the practical constraint. A Korean typeface carries a very large glyph set, so a full webfont is heavy, and the working answers are subsetting to the characters a page uses, a small number of weights chosen deliberately, or system faces for body text with a licensed face reserved for display. Decide this during design, because it determines how many weights the component library may use. Confirm who buys the licence and whether it covers web embedding.
Commerce Pages Here Are Built From Images, and That Is a Problem
Product detail pages in this market are commonly a single long strip of composed images containing all the copy, specifications and lifestyle photography. It is fast for a merchandising team to produce, it looks rich, and it is how shoppers expect a product page to feel. It is also unreadable to a screen reader, invisible to search, impossible to translate, and heavy to load for anyone outside a fast network.
A designer who understands the convention will not simply refuse it. The workable approach is a hybrid: keep the visual storytelling where imagery genuinely carries the message, but rebuild the specification tables, the sizing information, the delivery and returns terms and the headline claims as real text components with proper hierarchy. Ask a prospective studio how they have handled that tension, because the answer distinguishes a team that thinks about the whole page from one that produces artwork to a template.
Page length itself is a convention worth accepting. Long scrolling pages with many sections are normal and do not read as excessive here, so the design problem is sectioning and navigation within the scroll rather than compression.
Platforms Dictate Half the Component List
A brand's presence is rarely just a website. Discovery runs heavily through Naver, whose blog, shopping and place surfaces have their own content formats, so the structure of your own site has to work alongside those rather than pretend they do not exist. Sharing happens through KakaoTalk, which means the card that appears when a link is sent, with its title, thumbnail and crop, is a design asset that needs drawing rather than inheriting whatever the page happens to expose.
Checkout is built on simple payment wallets tied to those platforms as well as cards, and identity verification through a mobile carrier is a normal step in account creation and in some purchases. That verification adds a screen with its own waiting and failure states, and a design that assumes an email and password pair will be missing half the flow.
Addresses use a road-name system with a postcode lookup that is conventionally presented as a search overlay: the visitor searches, selects a result, then types the remaining detail. That overlay is an expected pattern and replacing it with a plain set of text fields makes a form feel amateur. Design the overlay, its no-result state and its return to the form.
Accessibility Is a Legal Requirement, Not a Preference
Web accessibility obligations here apply to public institutions and to a broad range of organisations providing services to the public, with a national set of guidelines derived from the recognised international success criteria and a certification mark that qualifying sites display. Any project touching a public body, education, healthcare or a large service provider should be designed against that baseline from the first wireframe.
The design consequences are direct, and they collide with local habits. Text rendered inside images fails immediately, which is another reason to restructure image-based commerce pages. Colour contrast has to hold in both Korean and any Latin text on the same screen. Focus states belong in the component library rather than being left to browser defaults. Form errors need to be described in words. Heading structure has to match the visual hierarchy rather than being chosen for size alone.
What a Foreign Brand Should Expect When Buying Design in South Korea
The listed pool of studios in this market is small compared with larger supplier countries, so the comparison you run will be narrow and should be qualitative. Look for teams that have shipped in your category, and be direct about whether you are buying a localisation of an existing brand system or an original design. Those are different engagements and they price differently.
Bilingual work deserves particular attention. An interface built in Korean and then translated tends to look loose in English because the component widths were set for square syllable blocks, while an English design translated into Korean looks cramped for the same reason in reverse. If both languages matter, say so at the start so the type scale and component sizing are drawn for both.
Seasonal commerce follows the lunar new year and the autumn harvest holiday, each with gift-buying peaks, campaign skins and shipping cut-off notices that have to be added and then removed cleanly. Treat that as a theme layer in the component system with documented tokens, not as annual redesign work.
Contract Points Worth Settling Early
Agree the working file format and get the source rather than flat exports, with named components and tokens, responsive rules and the empty, loading and error states drawn. Hold the design tool workspace under your own company account so a change of supplier does not cost you the file. Take written assignment of rights that covers employees and any freelance contributors, and settle font licensing in your name with the web embedding right confirmed.
Time zone favours an evening handoff for Western buyers rather than live collaboration, so agree a written review cadence instead of relying on calls, and ask for design reviews to be delivered as annotated files. A short paid pilot on one real template, reviewed by a Korean reader as well as by your own team, is the cheapest way to find out whether a studio composes screens or builds systems.
You can compare verified studios and client feedback across every market listed on Edvido, review app teams in the same market if the product is handset-first, and put one brief in front of a shortlist to see how each team reads the same problem.
