What Sizes Do Bifold Doors Come In? The Ultimate Sizing Chart<\/h2>\n\n\n\n

\u201cNominal size\u201d is the call\u2011out (e.g., 24″ \u00d7 80″), but the actual panels and the opening you need are different. Use the chart below; always verify with your manufacturer\u2019s spec.<\/p>\n\n\n\n

\n

\u201cActual Door Size\u201d is for standard interior, top\u2011track closet bifolds.<\/p>\n

\u201cFinished Opening\u201d is drywall\u2011to\u2011drywall (or jamb\u2011to\u2011jamb) after finishes.<\/p>\n

\u201cRough Opening\u201d is stud\u2011to\u2011stud, before drywall.<\/p>\n<\/div>\n\n\n\n

Typical formula of bifold doors:<\/h3>\n\n\n\n

For Single Bifold Doors<\/strong><\/p>\n\n\n\n

    \n
  • Finished Opening Width:<\/strong> Nominal Door Width<\/li>\n\n\n\n
  • Rough Opening Width:<\/strong> Nominal Door Width + 2 inches (This allows space for standard 3\/4″ wooden jambs and shims on both sides)<\/li>\n\n\n\n
  • Rough Opening Height:<\/strong> Nominal Door Height + 2-1\/2 inches (Allows for header jamb, top track, and floor clearance)<\/li>\n<\/ul>\n\n\n\n

    For Double Bifold Doors<\/strong><\/p>\n\n\n\n

      \n
    • Finished Opening Width:<\/strong> Nominal Door Width<\/li>\n\n\n\n
    • Rough Opening Width:<\/strong> Nominal Door Width + 2 inches<\/li>\n\n\n\n
