Create an ideal staircase with one simple measurement. Fine-tune the stairs to fit the space with an easy to use and understand, graphical interface.

Enter the total rise and the app calculates total run (base length or overall run), pitch (angle or slope), unit run (goings or tread), unit rise (rise or step height), and all other measurements. You can then adjust the total run to fit your available space or preferred tread materials. A unique feature to Delux Stairs fine-tunes the stringer to accommodate for differences in flooring thicknesses such as the tread thickness and upper and lower finished flooring. This ensures every step is identical, which is the difference between clumsy, dangerous, amateur stairs and professional-quality, comfortable, code-compliant stairs. Additional stair details, such as nosing, riser thickness and stringer dimensions are also calculated and adjustable.

Blueprint plans can be emailed in PDF which include platform position options, stringer peak positions, bottom step rise adjustments, top step run adjustments, and more.

The headroom clearance tool is unique to Delux Stairs and not only shows you top floor opening requirements with adjustable floor thicknesses, but also continuous headroom obstruction clearance from the top to the bottom of the stairs.

◎ Direct visual graphic feedback for quick, easy to understand design.
◎ Diagrams & information screens make the sometimes cryptic terms clear.
◎ Email the finished blueprints to the client or to yourself for printing.
◎ Takes flooring and tread thickness differences into account to ensure each step is identical to comply with building code.
◎ Presets for Outdoor (Decking), Indoor (Plywood or Hardwood) or Masonry (concrete) stairs.
◎ Perfect for open stringer and concrete designs & a great starting point for housed and box stairs.
◎ Headroom Clearance tool for determining top floor opening as well as continuous overhead obstruction clearance.

I got endless flak for having an “all-glass girly phone.” The GC says, “I better never see you texting your ‘boyfriends’ on my dime.” The GC was starting to measure the stairs for this project. He’s cheap so he dosn’t even let our top guys do that. I had just looked up construction apps last night and found this one, so I boght it on the spot. I put in the numbers and shortened the run to fit. The GC sees me do this and storms over becase he thinks I’m texting. I show him the app and he’s like, “no way this girly phone is right.” He goes back to his calculator. About 10 minutes later he asks, “What’d that thing say for treads?” We cut the stringer exactly like the app said to and it was spot on. At the end of the day, he was asking me where I got my iPhone. I’m on a different jobsite tomorrow that, guess what? It needs stairs cut.

I highly recommend terrific app! I have never needed to build custom stringers until I was in the middle of a mild sunroom upgrade. Store bought stringers were wrong heights. I downloaded this application and with some quiet time and reading directions thoroughly, I cut my own stringers (3) and found this app to be dead on accurate!!! It was so easy to use and the directions were great. After I understood better how the app calculates from top floor (assumes a riser to be first) I used the apps suggestion of adding approximately 7" to my height to get steps to calculate out for a flush top step with house floor (gives a nice quasi landing). The printable plans and such are all very accurate. Nice job to the creators of this very handy app.

simple, concise, and easy


The stairs down to the basement of our new place were scary and rotted. We needed access to the second bathroom and laundry. The landlord said he'd pay for material and give us a break on rent if we replaced them; but none of us knew how to build stairs. My dad came over one weekend with tools and helped remove the old stairs and haul the wood. Then came the "now what" moment. I'm so glad I found this app. The app let us know the stringer boards we bought were too short so we didn't cut them and could exchange them for longer ones. That alone saved us many times the cost of the app.
