Deck stairs stringers are the critical structural components that support the weight of the stairs on a deck. They are essentially the backbone of the staircase, running along either side of the steps to anchor the treads and risers. The proper layout of these stringers is fundamental to constructing a deck that is not only sturdy but also safe for everyday use. The key steps in laying deck stairs stringers include measuring and marking the location where the stairs will end, calculating the tread and riser dimensions to comply with local building codes, and cutting the stringer to fit these measurements. The layout process also involves securing each stringer in place and ensuring they are evenly spaced and aligned. A well-executed stringer layout ensures that the deck stairs are balanced and robust, minimizing the risk of collapse and maximizing the longevity of the structure. Properly laid out stringers create a safer walking surface, essential for high-traffic areas and adverse weather conditions, thus making your deck a reliable and enjoyable space.

Measuring and Marking the Stair Location
To ensure the accurate placement and sizing of your deck stairs, follow these detailed steps for measuring and marking the stair location:
- Determining the Stair Location and Dimensions:
- First, decide where on the deck you want the stairs to be. Consider the flow of your space and how the stairs will integrate with your garden or yard.
- Measure the total length and width available for the stairs, ensuring there's enough space for safe and comfortable use.
- Measuring the Deck Height:
- Use a tape measure to determine the vertical distance from the top of the deck down to the ground. This measurement is crucial for calculating the number of steps needed.
- The total rise, which is the height from the ground to the deck surface, will help you figure out how many risers (or vertical sections) your stairs need. Standard riser height is usually about 7 inches.
- Marking the Stair Location:
- With the location and total rise known, use chalk or a pencil to outline where the stairs will begin and end on the deck surface.
- Mark the edge of the deck where the top stair will meet the deck, and note where the bottom stair will rest on the ground to ensure alignment and stability.
These steps will help you lay a solid foundation for building safe and aesthetically pleasing deck stairs.

Calculating Stair Tread and Riser Dimensions
Accurate calculation of stair tread and riser dimensions is essential for creating a safe and comfortable staircase on your deck. Here's how to get these measurements right:
- Understanding Recommended Dimensions:
- Stair Treads: These are the horizontal parts of the stairs that you step on. The recommended depth for treads is at least 10 inches, as it provides sufficient space for the average adult foot to rest completely.
- Stair Risers: These are the vertical sections between each tread. The ideal riser height is usually about 7 inches, which is comfortable for the average stride, minimizing strain when ascending or descending the stairs.

- Calculating Tread Depth and Riser Height:
- To begin, measure the total height from the deck surface to the ground (total rise).
- Divide this measurement by the ideal riser height (about 7 inches) to determine the number of steps needed.
- If the division results in a fraction, round up to the next whole number to determine the total number of risers, and then recalculate the riser height to distribute the total rise evenly.
- Compliance with Building Codes:
- Check your local building codes for any specific requirements regarding stair construction.
- Ensure that both the tread depth and riser height fall within the local regulatory standards to avoid potential hazards and legal issues.
- It’s also advisable to confirm whether additional features like handrails or specific materials are mandated by your local code.
By following these guidelines, you will ensure that your deck stairs are not only compliant with safety regulations but also comfortable for daily use.

Laying Out the First Stringer
Laying out the first stringer correctly is crucial for the stability and alignment of your deck stairs. Follow these steps to ensure your stringer is accurately positioned and cut:
- Positioning the First Stringer:
- Place the stringer at the location previously marked on the deck. Ensure it aligns perfectly with the marks indicating the edge of the deck and the bottom step.
- Marking Tread and Riser Locations:
- Using the dimensions calculated for tread depth and riser height, mark the stringer for where each tread and riser will be. You can use a framing square and stair gauges to transfer these measurements accurately onto the stringer.
- Ensure each mark is clear and precise, as this will dictate the structural integrity of your stairs.
- Cutting Notches for Treads and Risers:
- Before cutting, double-check each measurement to ensure no errors.
- Use a circular saw to make the initial cuts for each tread and riser notch. Finish each cut with a hand saw to reach the corners that the circular saw cannot fully clear.
- Smooth out the notches with a chisel and hammer if necessary to make sure they are clean and even, which will provide a secure fit for the treads and risers.
By carefully following these steps, your first stringer will be accurately prepared, setting a solid foundation for the remaining components of your deck stairs.

Laying Out Additional Stringers
Properly laying out additional stringers ensures the durability and safety of your deck stairs. Follow these steps to accurately position and prepare the additional stringers:
- Determining Stringer Spacing:
- Measure the total width of the stairs to decide on the optimal spacing between stringers. Typically, stringers should be spaced about 16 to 24 inches apart center-to-center, but this can vary based on the width of the stair and the thickness of the treads.

- Marking Locations for Additional Stringers:
- On the deck, mark the locations for each additional stringer using the determined spacing. Ensure each mark is aligned with the top and bottom of the stairs to maintain uniformity across the structure.
- Use a level or a straight edge to ensure that the marks are vertically aligned with those of the first stringer for consistency.
- Repeating the Marking and Cutting Process:
- Transfer the tread and riser measurements to each new stringer using the same method employed for the first stringer.
- Carefully cut the notches with a circular saw and finish with a hand saw as before, ensuring each cut is precise for a stable fit.
These steps will help you efficiently lay out additional stringers, contributing to a sturdy, well-balanced deck stair structure.

Securing the Stringers to the Deck
Securing the stringers to the deck is a crucial step for ensuring the stability and safety of your deck stairs. Here’s how to properly attach the stringers:
- Attaching the First Stringer:
- Position the first stringer against the deck at the marked location. Use heavy-duty fasteners such as lag screws or carriage bolts to secure the stringer to the deck frame.
- Ensure that the fasteners are long enough to penetrate deeply into the deck framing for a secure hold.
- Leveling and Aligning the Stringer:
- Check that the stringer is perfectly level horizontally and aligned vertically with your markings. Adjust as necessary before fully securing it.
- Use a spirit level for accuracy and adjust the position of the stringer until it’s perfectly aligned.
- Securing Remaining Stringers:
- Repeat the process with the additional stringers, ensuring each is spaced correctly from its neighbors according to your earlier measurements.
- Double-check the alignment and level of each stringer as you go, making adjustments as needed before fully securing them.
By carefully following these steps, you’ll ensure that your deck stairs are solidly constructed and provide safe, long-term use.

Installing the Stair Treads
Installing stair treads correctly is key to ensuring a safe and visually appealing staircase on your deck. Follow these steps to properly install the treads:
- Cutting the Stair Treads:
- Measure and cut each stair tread to the required length and width to fit snugly between the stringers. Use a circular saw for a clean, straight cut.
- Securing the Treads to Stringers:
- Position each tread in the notches cut into the stringers. Secure the treads using exterior-grade screws or galvanized nails, which provide durability and resistance to weather conditions. Drive the fasteners through the tread and into the stringer at both ends and the middle if necessary.
