DeckSketch 3D is the most complete tool to design, plan and estimate the cost of your balcony, patio or wood deck. Whether you're a passionate DIYer or a contractor, this app guides you from the first sketch to the job site. DRAW YOUR DECK IN 2D Trace the outline of your deck directly on your screen. Create complex shapes, add multiple levels at different heights and attach the structure to your house. Add elements like a hot tub, round or rectangular pool, stairs, pergolas and guardrails with gates. View the framing in real time with joists, beams and posts. VISUALIZE IN REALISTIC 3D Instantly switch from your 2D drawing to an interactive 3D view. Explore your project from three angles: the finished rendering with colors and materials, the framing structure with posts, beams and joists, and the underside view to check structural integrity. Rotate, zoom and pan the view with smooth touch gestures. CUSTOMIZE EVERY DETAIL Choose from multiple surface materials: pressure-treated wood, natural cedar or composite in 10 trending shades (charcoal grey, walnut, driftwood, mahogany and more). Select the railing style (aluminum, tempered glass, treated wood or composite) and foundation type (sonotubes, pad footings or helical piles). Add a pergola with 5 roofing options: open rafters, polycarbonate, retractable shade, solid roof or metal roofing. SMART STAIR CALCULATOR Simply enter the total height and desired width. The app automatically calculates the number of steps, the rise and run of each step, the stringer length and the number of stringers required. A detailed cut diagram guides you to cut your stringers with precision. Automatic building code compliance check (IRC R311.7). COMPLETE MATERIALS AND CUT LIST Get a detailed list of everything you need: foundations, posts, beams, joists, decking boards, stringers, treads, railings, hardware, bolts and screws. The optimized cut list shows each piece with its exact dimensions and purpose. Minimize waste with the cut plan that organizes your cuts on standard-length boards. PRICE ESTIMATES BY STORE Compare estimated prices at hardware stores near you: Home Depot, Lowe's, Rona and other retailers. Use the built-in GPS to find the nearest store or sort by price to save money. Available in Canada, the United States, France, the United Kingdom, Germany and Belgium. Prices are adjusted monthly based on the materials inflation index. PROFESSIONAL PDF PLANS Generate a complete multi-page PDF package ready for the job site or permit application: floor plan with dimensions, framing plan, foundation plan, side elevation, stair detail, railing detail, pergola detail, materials list, cut list, optimized cut plan, step-by-step assembly guide and code compliance tips. Print or share directly from the app. BUILDING CODE COMPLIANT All calculations follow IRC R507 (beam sizing, post spacing) and IRC R311.7 (stairs) standards. Compatible with North American and European standards. Choose between North American lumber sizes (2x6, 2x8, 2x10) or European sizes (45x95 mm, 45x145 mm). Imperial or metric system based on your preference. FREE TO START Full 2D drawing, 3D view and stair calculator are free. Upgrade to Pro to unlock precise measurements, the complete cut list, price comparison, PDF plans and unlimited saves.

Deck Calculator & Planner

Read full description

Planning a deck? Type the width, depth and height. Deck Calculator & Planner draws the deck to scale and lists everything you need: joists, beams, posts, footings, concrete, decking, screws, railing and stairs. Free to plan. One purchase unlocks PDF export, the cut list and cost totals. No subscription. No account. What the app gives you: - A scaled plan you can see and adjust as you change the size, attached or freestanding - A full material list, grouped by framing, footings and concrete, decking and hardware, with your own prices and a running total - Stairs worked out for you: rise, run, tread count and stringers - A joist and beam check against published span tables, with a flag when a choice is outside the table - Railing counted out: posts and balusters, spaced to keep gaps under 4 inches - A PDF you can print or send, with a cut list page for the lumber yard Deck Planner helps you plan and estimate. It is not engineering advice and it does not replace your building department, a licensed engineer or a contractor. Span and footing checks come from published prescriptive tables for typical conditions. Your town may use a different code edition, snow load, frost depth or soil value. Most decks need a permit. Check with your local permit office before you buy materials or build.
