How do you calculate stringer length for stairs?
✅ To calculate stringer length, use this quick method:
Find the total rise (height) and total run (depth) of your stairs.
Use the Pythagorean theorem:
Stringer Length = √(Total Rise² + Total Run²)
Or use an online stair calculator to do it automatically.
How do you convert a decimal to a fraction in carpentry?
✅ In carpentry, convert decimals to fractions like this:
Take the decimal part (e.g., .75).
Multiply it by 16 (for 1/16 inch measurements).
Round to the nearest whole number and put it over 16.
Example: .75 × 16 = 12 → 12/16 = 3/4 inch
Many online calculators do this automatically for easier measuring.
Is there an alternative to Dailylifetools.com for online carpentry calculators?
✅ Yes! An excellent alternative is Mycarpentry, which offers a variety of free online tools for construction calculations, including stair design, roof pitch, and framing help
What is the formula for calculating stairs?
For interior stairs, use this rule-of-thumb: Riser + Tread = 17.5 inches (7.5 inches for riser height, 10 inches for tread depth), and Riser * Tread = 75 inches.
What is the golden rule for stairs?
The golden rule for stairs says that if you double the rise and add the going, it should be between 24 and 25 inches. This makes stairs comfortable for most people.
