The Fixin' Post – 400mm Stud Spacing Technique for Plasterboard & Joist Layout

Accurate stud spacing is crucial when framing walls, partitions, or joists. In the UK, 400mm centres are a standard choice—ideal for plasterboard installation and structural reliability. But measuring each gap with a tape measure can be slow and repetitive. This post shares a clever 400mm stud spacing technique for plasterboard that speeds up your workflow, improves consistency, and helps you get the job done right. Whether you're a tradesperson or DIYer, this tip makes stud work faster and more efficient.

The 353mm Trick: Save Time, Stay Consistent with Stud Spacing

Looking for a more efficient way to position noggins between studs set at 400mm centres? Try this simple yet effective stud spacing technique for plasterboard.

• Cut a timber spacer to 353mm.  This measurement accounts for the 47mm width of standard CLS timber, giving you the exact distance between the inner faces of studs.

• Use the spacer as a template. It allows you to quickly and consistently position your noggins (horizontal braces between studs) without reaching for the tape measure every time.

This time-saving method improves accuracy, enhances consistency, and supports a more efficient stud layout—ideal for both DIYers and UK tradespeople working with plasterboard framing.

Why It Works

• Efficiency: Eliminates the need to pull out the tape measure for every noggin placement.

• Consistency: Ensures all noggins are perfectly aligned between studs set at 400mm centres.

• Accessibility: Ideal for DIYers aiming for professional-level results without complex tools or calculations.

  
  

This stud spacing technique for plasterboard streamlines your workflow and delivers reliable results—whether you're framing walls, partitions, or joists.

Bonus Tip

If you're working with different stud widths or centre spacings—such as 600mm centres—you can still apply this efficient technique. Simply measure the distance between the inner faces of the studs, accounting for the timber width, and cut your spacer to match. This ensures consistent noggin placement across any framing layout, whether you're using CLS timber or alternative sizes.

This adaptable approach keeps your stud work precise and your plasterboard installation smooth—no matter the spacing.
