Key Difference

• The main difference between tartan and plaid is that the word "tartan" refers to the crisscross pattern found on traditional Scottish dress. "Plaid" refers to the blanket-like garment worn before the kilt was invented.
  
  

Origins

• Both tartan and plaid originated in Scotland as early as the 16th century.
  
  

Fabrication

• The tartan pattern is created by weaving threads at right angles, producing solid colors or lighter shades. The weaving of tartan produces material. The plaid is formed with the material cut and stitched into blankets measuring about 3 to 6 meters.
  
  

Significance

• Tartan patterns are traditionally associated with various Scottish clans, and each clan possesses its own pattern of tartan to distinguish itself from others. This tradition continues today. Plaid, on the other hand, is a symbol of Scottish culture, appearing in traditional Scottish highland dress, and now reserved for ceremonial and formal events.
  
  

Use

• While plaid is now uncommon, tartan has become popular among designers as a form of fashion.
