বাংলাদেশে অনলাইন শপিং-এ সবচেয়ে বড় “drop-off” হয় যখন কাস্টমার সাইজ বুঝতে পারে না বা পণ্যের রঙ/ভ্যারিয়েন্ট বাছাই করতে গিয়ে কনফিউজড হয়ে যায়। এখানেই Size Chart & Variant UI Design কনভার্সন বাঁচায়—first try-তেই right size, স্পষ্ট variant options, কম রিটার্ন/এক্সচেঞ্জ, আর বেশি trust। আজকের এই গাইডে আমরা দেখাবো কীভাবে BD বাজার, Bangla-English bilingual users, mobile-first traffic, এবং WooCommerce/Shopify stack মাথায় রেখে আপনি বিজয়ী Size Chart + Variant UX বানাবেন—BD IT CENTER-এর প্রো-টিপস সহ।
Mobile-first BD market: অধিকাংশ ট্রাফিক মোবাইল থেকে; তাই one-tap size guide with sticky access is a must.
Bangla & English users: Dual unit (inch/cm) toggle, Bangla labels + English shorthand (e.g., “লম্বা/Height (cm|inch)”).
Variant noise: Color, size, fit, fabric, bundle—সব এক স্ক্রিনে ছড়িয়ে দিলে confusion হয়; progressive disclosure দরকার।
Trust & returns: Clear measurements, fit notes, and model reference reduce returns and boost conversion.
Above-the-fold “Size Guide” button (icon + text), PDP-এর price ও CTAs-এর পাশে।
Sticky micro-link near size options: “Need help? Size Guide”.
Mobile-এ bottom sheet modal (swipe-friendly), desktop-এ clean modal / side drawer।
টেবিলের primary columns: Body area (Chest, Waist, Hip), Garment measurements, Recommended height/weight range।
Unit toggle: cm↔inch। Default cm (BD context) কিন্তু toggle one-tap।
Model reference: “Model 5'6” / 62kg wearing M—Relaxed fit”.
Fit notes: “Slim fit—উপরে টাইট; normal build হলে one size up”.
Quick questions (2-step): Height + Weight → suggest likely fit (e.g., M or L).
Edge cases: Broad shoulders / maternity / modest fit → “consider one size up”.
Variant dependency: Color change করলে size availability real-time update (out-of-stock states)।
Incompatible selection guard: Invalid combo হলে clear toast: “This size is not available in ‘Olive Green’.”
বাংলা microcopy + short English: “সাইজ গাইড দেখুন (Size Guide)”।
Buttons ≥44px, proper contrast, keyboard focus ring, ARIA labels (e.g., aria-expanded for accordions)।
Visual color swatches (not only text), with tooltip name: “Midnight Navy”।
Size as buttons, not select dropdowns; show stock state (“M – Low stock”).
Auto-select first available variant to show price/sku/images instantly.
Gallery binding: Color নির্বাচন করলে image set auto-update।
Bundle/Set variants: “Buy 2 & Save” as separate variant tier—clarity over cleverness।
Price clarity: Regular, sale, and per-variant pricing—one place, one format।
Shipping & exchange micro-block right under size selector: “Free size-exchange within 7 days (BD only)”.

টিপ: PDP-এর footer-এ “Need a custom site?” CTA থেকে উপরের Services-এ deep-link করলে topical relevance ও internal equity বৃদ্ধি পায়।
Q1. Size chart কোথায় রাখলে conversion বাড়ে?
A. Price/CTA এর পাশে above-the-fold বোতাম + size options-এর কাছে sticky micro-link, mobile-এ bottom-sheet modal—এটাই proven layout।
Q2. cm নাকি inch—কোন unit default হওয়া ভালো?
A. BD context-এ cm default, কিন্তু one-tap toggle রাখুন। Toggle use করলে users feel in control।
Q3. Height/Weight suggestor কি আবশ্যক?
A. Apparel-এ helpful—first-time buyers-এর confusion কমে, returns down, trust up।
Q4. Variant image binding কতটা জরুরি?
A. Color-wise gallery না বদলালে mismatch-এর fear বাড়ে। Auto-binding must-have।
Q5. Returns কমানোর UX কী?
A. Clear measurements, model reference, fit notes, easy exchange policy micro-copy (e.g., “7-day size exchange”)।
Q6. WooCommerce/Shopify-এ কোডিং heavy?
A. না; modern theme + lightweight JS দিয়ে native-like feel সম্ভব। আমরা আপনার stack অনুযায়ী optimize করি।
