Designing for Tamil and multilingual audiences

A lot of what we build is used by people who think, search and shop in Tamil — traders checking cardamom prices, shoppers browsing Chettinad cotton, families sharing reactions in their own language. Designing for them well is not a translation task at the end of a project. It changes typography, layout, search and SEO from the start.

These are the practical rules we follow. Most apply equally to Hindi, Telugu, Malayalam, Kannada and other Indian languages.

Typography: give the script room

Tamil glyphs have tall ascenders, deep descenders and vowel signs that sit above and below the base letters. Settings that look fine in English will clip or crowd Tamil text.

• Increase line height. Where English body text sits comfortably around 1.5, Tamil usually needs more. Test with real paragraphs, not a single word.
• Choose fonts designed for the script. System fallbacks vary wildly between devices. Well-designed open fonts such as Noto Sans Tamil, Mukta Malar or Catamaran render consistently.
• Pair deliberately. If your brand font is Latin-only, pick a Tamil face with similar weight and proportions so mixed-language screens feel like one design.
• Avoid tight letter-spacing and all caps tricks. Tamil has no uppercase, and negative tracking breaks combined characters.
• Load only what you need. Subset fonts and load the Tamil font only on pages that use it; Indic fonts can be large.

Layout: plan for longer strings

Tamil translations are often noticeably longer than their English source. A button that fits "Buy now" may not fit its translation.

• Let buttons and labels grow; never set fixed widths on text containers.
• Test navigation with the longest real labels.
• Keep icons next to text rather than replacing text — icons alone are ambiguous across audiences.
• Leave space in cards and tables for text to wrap onto two lines without breaking the layout.

Never put words in images

Text inside images can't be translated, searched, zoomed or read by screen readers, and it is often blurry on low-resolution phones. Banners with Tamil text baked into a JPEG are a common mistake on Indian ecommerce sites. Put the text in HTML over the image instead.

Search: people type in two scripts

Many users search in romanised Tamil ("Tanglish") as often as in Tamil script — "pattu pudavai" as well as the Tamil spelling, or simply the English word. Your store search should handle all three.

• Add synonyms and transliterations to product tags or search settings.
• Include common English terms alongside Tamil ones in product titles where natural.
• Test the search box with the words your customers actually type — ask your sales team.

Numbers, dates and money

• Use Indian digit grouping for prices: ₹1,00,000, not ₹100,000.
• Show dates in a format your audience reads naturally, and spell out months where ambiguity is possible.
• Keep units familiar: grams and kilograms for spices, centimetres and metres for fabric.

Accessibility and HTML basics

• Set the page language with the lang attribute (ta for Tamil) and mark mixed-language passages, so screen readers pronounce them correctly.
• Keep contrast high; thin strokes in some Indic fonts lose legibility on light greys.
• Make touch targets generous — many users are on budget phones with small screens.

SEO for multilingual sites

• Give each language its own URL (for example, /ta/ for Tamil) rather than switching language with JavaScript.
• Add hreflang tags so search engines show the right version to the right audience.
• Translate titles, meta descriptions and image alt text — not just body copy.
• Write content for local queries; a direct translation of an English page rarely matches how people search in Tamil.

Content: translate meaning, not words

Machine translation is a useful first draft and a poor final one. Tone matters: formal Tamil can feel distant for a playful brand, while very colloquial Tamil can feel wrong for a hospital. Have a fluent speaker who knows the brand review every screen.

Testing with real users and devices

Multilingual problems rarely show up on a designer's laptop. They show up on a budget Android phone, with the system font set larger than default, on a 4G connection in a small town. Build that into testing:

• Test on low- and mid-range Android devices. Font rendering and performance differ noticeably from flagship phones.
• Increase the system font size. Many users do; layouts that survive it will survive long translations too.
• Watch someone search. Ask a customer to find a product in the way they normally would. You'll learn more about transliteration from five minutes of watching than from any keyword tool.
• Check shared links. When a Tamil page is shared on WhatsApp, the preview title and description should be in Tamil and not truncated mid-character.
• Read it aloud. A native speaker reading the interface aloud catches awkward phrasing that looks fine on screen.

Where to start if your site is English-only

You don't have to translate everything at once. Start where language matters most to your customers:

1. Product names and descriptions for your best sellers.
2. Checkout, delivery and returns information — where confusion costs orders.
3. Support pages and WhatsApp quick replies.
4. Marketing pages and the blog.

Each step is useful on its own, and each teaches you how your customers read and search before you invest in the next.

A quick checklist

1. Script-appropriate fonts, subsetted, with generous line height.
2. No fixed-width text containers; test with the longest labels.
3. No text inside images.
4. Search that understands Tamil script, Tanglish and English.
5. Indian number formatting.
6. Correct lang, separate URLs and hreflang for each language.
7. A native speaker reviews the final copy.
