How to Install the First Sheet of Drywall: A Step-by-Step Guide

Installing the first sheet of drywall is a critical step in the drywall installation process, as it sets the foundation for the entire project. Properly positioning and securing the first sheet ensures that subsequent sheets align correctly and that the finished result is smooth and professional. In this article, we will provide a step-by-step guide on how to install the first sheet of drywall effectively.

Tools and Materials:

Before you begin, gather the following tools and materials:

  • Drywall sheets
  • Drywall screws
  • Cordless drill with a screwdriver bit
  • Drywall T-Square
  • Utility knife
  • Pencil or marker
  • Tape measure
  • Drywall lift (optional, for ceilings)

Step 1: Measure and Mark

  1. Measure the height of the wall from the floor to the ceiling, starting from one corner. Mark this measurement on the edge of a drywall sheet, ensuring that it’s parallel to the long side of the sheet.
  2. Use a Drywall T-Square to extend the measurement line across the width of the drywall sheet. This line will serve as a guide for cutting the sheet to the correct height.

Step 2: Cut the Drywall Sheet

  1. Score the drywall sheet along the marked line using a utility knife. Apply firm, even pressure to create a shallow groove in the paper facing.
  2. Once the groove is established, bend the drywall sheet along the scored line to break it cleanly. Be sure to support both sides of the sheet to prevent it from snapping unevenly.
  3. Carefully cut through the paper backing on the opposite side to complete the cut.

Step 3: Position the First Sheet

  1. With the first sheet cut to the correct height, position it in the corner of the wall or ceiling where you intend to start the installation. Ensure that the factory (untapered) edge of the drywall sheet is flush against the corner.
  2. For walls, align the top edge of the drywall sheet with the ceiling framing or the top plate of the wall.
  3. For ceilings, use a drywall lift to hold the sheet in place while you secure it. Position the lift under the sheet, raise it to the desired height, and lock it in place.

Step 4: Secure the First Sheet

  1. Begin securing the drywall sheet by driving drywall screws into the framing or ceiling joists. Start with the top corner and work your way down the sheet, spacing screws approximately every 12 inches along the framing members.
  2. Ensure that the screws are countersunk slightly below the surface of the drywall but not over-tightened, as this can damage the gypsum core.
  3. Repeat the process for the remaining corners and edges of the sheet, ensuring that it is securely fastened.

Step 5: Check for Level and Plumb

  1. Use a level to check that the first sheet is both vertically plumb and horizontally level. Adjust the positioning of the sheet as needed to achieve a precise fit.
  2. Ensure that the first sheet is flush with adjacent walls or ceiling surfaces.
  3. If necessary, use shims or spacers to correct any misalignment or irregularities.

Step 6: Continue with Additional Sheets

  1. Once the first sheet is securely in place and level, you can proceed to install additional drywall sheets, working your way across the wall or ceiling.
  2. Stagger the seams between sheets to create a more stable and visually appealing layout. Use drywall screws to attach the sheets to the framing or ceiling joists.
  3. Ensure that the edges of the drywall sheets are closely aligned and that there are no large gaps between them.


Installing the first sheet of drywall correctly is a crucial step that sets the tone for the entire project. By following these step-by-step instructions, you can ensure that the first sheet is positioned accurately, securely fastened, and level. With the foundation in place, you can proceed with the rest of the drywall installation, ultimately achieving a smooth and professional finish for your construction or renovation project.
