Best Interior Design Courses in 2026: Top 10 for All Levels

Interior design has never been more learnable from home. Whether you want to redesign your own living room, build a freelance decorating side hustle, or train toward a professional career, there is now a course for every budget and ambition, from a free Alison diploma to a MasterClass taught by one of the most celebrated designers alive.

The catch is that the field sprawls. “Interior design” can mean color theory and styling, or it can mean CAD floor plans and photorealistic 3D rendering. The ten courses below are split across both ends of that spectrum and across every major platform we cover, so you can match the training to the outcome you actually want. We have flagged which are paid, which are free, and exactly who each one is best for.

After reviewing the leading interior design programs across MasterClass, Domestika, Coursera, Udemy, Skillshare, LinkedIn Learning and Alison, here are our top picks for 2026.

The 10 Best Interior Design Courses in 2026

1. Kelly Wearstler Teaches Interior Design (MasterClass), Top Pick

Platform: MasterClass | Level: All levels | Duration: ~3 hours (15 lessons) | Certificate: No | Cost: MasterClass membership (free trial via annual plan)

Kelly Wearstler is one of the most influential interior designers working today, and she was the very first to teach the subject on MasterClass. Across fifteen lessons she walks through how she approaches color, balance and symmetry, material selection, and the art of making a space tell a story. This is not a technical CAD course: it is a masterclass in taste, point of view, and the creative confidence that separates a decorated room from a designed one.

It is the best pick for anyone who wants to think like a designer rather than just follow rules. Wearstler is candid about her process, including how she builds a “vibe tray” of materials to keep a project fluid and how she treats furniture as sculpture. Beginners will be inspired and intermediate designers will steal a dozen ideas, though if you need step-by-step software training you will want to pair this with one of the technical picks below.

Best for: Aspiring and practicing designers who want to develop genuine creative vision and taste from a world-class practitioner.

2. Interior Design for Beginners by STUDIOLAV (Domestika)

Platform: Domestika | Level: Beginner | Duration: ~2 hours | Certificate: Yes | Cost: Paid (frequently discounted)

Taught by the London-based studio STUDIOLAV, this is one of the most approachable on-ramps to the profession anywhere online. It introduces what an interior designer actually does day to day, then moves through the essential concepts and tools you need to take an idea from a rough concept to a physical space. Domestika’s production values are excellent, and the project-based structure means you finish with something real rather than just notes.

Because Domestika began as a Spanish-language creative community, its design catalog has a distinctly European, style-forward sensibility that you will not find on more corporate platforms. If you are a beginner who learns by doing and wants a course that feels like sitting in a working studio, this is the one to start with.

Best for: Total beginners who want a beautifully produced, project-driven introduction with a creative-studio feel.

3. Become an Interior Designer: Interior Design Complete Course (Udemy)

Platform: Udemy | Level: Beginner to Intermediate | Duration: ~10 hours | Certificate: Yes (completion) | Cost: Paid (often on sale)

This is the most complete single-course foundation on this list. It covers the full arc of a design project, examining what it takes to be an interior designer, the broad considerations every designer weighs, and the end-to-end process from brief to finished room. With around ten hours of material it goes deeper than the quick primers, making it a genuine career starting point rather than a taster.

Udemy’s lifetime-access model means you can work through it at your own pace and return to specific modules when a real project demands them. Watch the per-section ratings and recent reviews before buying, as Udemy quality varies, but this title has earned its place as a reliable, comprehensive beginner-to-intermediate option that you can usually grab for the price of a takeaway.

Best for: Self-starters who want one thorough, affordable course that takes them from zero to a working understanding of the whole design process.

4. Maya 3D: Architecture & Photorealistic Interiors (Coursera)

Platform: Coursera | Level: Intermediate | Duration: ~3-4 months (self-paced) | Certificate: Yes | Cost: Coursera subscription (Coursera Plus eligible)

Modern interior design increasingly lives in 3D, and this specialization is the most rigorous visualization training on our list. Across its courses you model and texture complete interior projects, bedrooms, bathrooms, kitchens and living spaces, and finish each with a render-ready architectural visualization in Autodesk Maya. By the end you can design, model, texture, light and render fully detailed 3D interiors, the exact skill set studios pay for.

This is not where a styling-focused beginner should start, but for anyone aiming at a professional or technical role it is enormously valuable. Because it sits on Coursera, a single subscription can also cover the 3ds Max and AutoCAD interior specializations, so if you are serious about CAD it is the most cost-effective way to learn several tools at once.

Best for: Intermediate learners and career-changers who need professional-grade 3D modeling and photorealistic rendering skills.

5. Easy Interior Design: Create a Space for Function and Flow (Skillshare)

Platform: Skillshare | Level: Beginner | Duration: ~1.5 hours | Certificate: No | Cost: Skillshare membership (free trial)

Taught by designer Demetrius Robinson, this class is built for people tackling a design project for the first time. It is a step-by-step foundation in how to make a room both work and feel good, prioritizing function and flow over decoration for its own sake. In about ninety minutes you get a practical framework you can apply to your own home that same afternoon.

Skillshare’s strength is exactly this kind of short, hands-on, project-led class, and a single membership unlocks hundreds more on styling, color and small-space living. If you want momentum and a quick win rather than a months-long commitment, start here and branch out into the platform’s deeper interior design catalog as your confidence grows.

Best for: First-time decorators who want a fast, practical framework they can apply to a real room immediately.

6. Diploma in Interior Design (Alison), Best Free Option

Platform: Alison | Level: Beginner | Duration: ~15 hours | Certificate: Yes (paid certificate option) | Cost: Free

Alison’s diploma is the strongest genuinely free option on this list. It gives an overview of interior design as both a discipline and a career, covering project planning, client communication, and how to work with color, surface materials, textures, textiles, accessories and furniture. You can complete it in roughly fifteen hours, and while learning is free, you can optionally pay for an official diploma certificate if you want something to show.

The trade-off for zero cost is a more text-and-slide format than the video-rich paid platforms, so it rewards self-motivated learners. But as a no-risk way to confirm interior design is right for you, or to add a structured credential to a portfolio: it is hard to beat. We always recommend starting free before paying, and this is the free course we point most beginners to. View the Alison diploma here.

Best for: Budget-conscious beginners who want a structured, certificate-bearing course at no cost.

7. Revit for Interior Architecture (LinkedIn Learning)

Platform: LinkedIn Learning | Level: Intermediate | Duration: ~3 hours | Certificate: Yes | Cost: LinkedIn Learning (free trial)

Revit is a core tool in professional interior architecture, and this course teaches it specifically for interiors: organizing your project browser, assigning finishes to rooms, and creating new materials and custom wall types. It is concise and practical, aimed at designers who already grasp the basics and now need the software fluency that real firms expect on a resume.

LinkedIn Learning courses come with a free trial and a shareable certificate that lands directly on your LinkedIn profile, which is useful if you are job-hunting. Treat this as a free starting point, then move into a deeper CAD specialization if you want to go pro. See the course on LinkedIn Learning.

Best for: Designers who need job-ready Revit skills for interior architecture and want a credential on their profile.

8. 3ds Max Interior Design: Model & Create Spaces (Coursera)

Platform: Coursera | Level: Beginner to Intermediate | Duration: ~10 hours | Certificate: Yes (paid) | Cost: Free to audit

This Coursera course is built for interior design students, architects and 3D enthusiasts who want professional modeling technique. You import and construct floor plans, manipulate vertices and edges for precision modeling, design structural walls and openings, refine window geometry, and build custom furniture such as sofas in 3ds Max. It is hands-on and grounded in real-world projects rather than abstract theory.

Crucially, you can audit the course for free, watch the lessons and follow along at no cost, paying only if you want the graded assignments and certificate. That makes it one of the best zero-risk ways to try industry-standard CAD before committing. Audit it free on Coursera.

Best for: Learners who want to try professional CAD modeling for interiors without paying upfront.

9. The Complete Introduction to Interior Design Course (Udemy)

Platform: Udemy | Level: Beginner | Duration: ~3 hours | Certificate: Yes (completion) | Cost: Paid (often on sale)

If the ten-hour complete course at number three feels like too big a commitment, this shorter Udemy title is the lighter alternative. It requires no prior knowledge and gives a focused tour of what interior design involves, the key aspects designers need to know, the broad considerations they weigh, and the design process itself, all in about three hours.

It works well as a primer you finish in an evening to decide whether the field is for you, before investing in a deeper program. As with any Udemy course, check the recent reviews and preview a few lessons first. Preview it on Udemy.

Best for: Curious beginners who want a quick, low-commitment overview before going deeper.

10. The Ultimate SketchUp Course for Interior Designers (Skillshare)

Platform: Skillshare | Level: Beginner to Intermediate | Duration: ~6 hours | Certificate: No | Cost: Skillshare membership (free trial)

SketchUp is the friendliest 3D tool for interiors, and this course by Anna Rangel is built specifically for designers and students. It covers space planning, 3D modeling and presenting your ideas, making it an ideal bridge between styling fundamentals and heavier CAD tools like Revit or 3ds Max. At around six hours it is thorough without being intimidating.

Because it lives on Skillshare, a free trial lets you take the whole course at no cost, and the same membership opens up dozens of related space-planning and rendering classes. It is our pick for the learner who has the design ideas but needs a fast, visual way to plan and present rooms. Find it on Skillshare.

Best for: Designers who want approachable 3D space-planning skills with SketchUp.

How to Choose the Right Interior Design Course

Start with your outcome, not the course. If you want to redesign your own home, a short styling class like the Skillshare or Domestika picks will get you moving fast. If you are aiming at a freelance side hustle or a career change, prioritize a comprehensive program plus at least one CAD tool, because clients and employers expect both taste and technical drawing.

Next, weigh cost against how you learn. The free Alison diploma and the free-to-audit Coursera courses let you test the waters at zero risk, which is always the smart first move. Subscription platforms like MasterClass, Skillshare and Coursera Plus make sense once you know you will take several courses, since one fee covers many. Single Udemy and Domestika purchases are best when you want to own one specific course outright. Whatever you choose, finish one course and complete its project before buying the next, a portfolio piece beats a pile of half-watched lessons every time.

Frequently Asked Questions

Can I learn interior design online with no experience?

Yes. Several courses here, including the Alison diploma, the Domestika beginner course and the Skillshare classes, assume zero background and start from first principles. Begin with a free or short option to build confidence, then move into a comprehensive program once you know you enjoy it.

Are there genuinely free interior design courses?

Absolutely. Alison’s Diploma in Interior Design is completely free to study, and Coursera’s 3ds Max and other interior courses can be audited free: you only pay if you want the graded certificate. These are the best no-risk ways to start.

How long does it take to learn interior design?

A short styling class takes one to two hours, a solid beginner foundation around ten to fifteen hours, and professional CAD specializations a few months of part-time study. Most people get usable results for their own home within a weekend and reach a freelance-ready level in a few months of consistent practice.

Will an online course get me a job or freelance clients?

An online certificate alone rarely lands a role, but the skills and portfolio you build absolutely can. Employers and clients care most about a strong project portfolio plus working knowledge of tools like SketchUp, Revit or 3ds Max. Pair a design-fundamentals course with a CAD course and build real sample projects to show.

Do I need to learn CAD software, or just styling?

It depends on your goal. For decorating your own space, styling and color skills are enough. For professional or freelance work, CAD fluency is expected, SketchUp is the easiest entry point, with Revit and 3ds Max valued for more technical roles.

Ready to design your first space? Pick one course that matches your goal, the free Alison diploma if you are testing the water, or Kelly Wearstler’s MasterClass if you want world-class inspiration, and commit to finishing it with a real room as your project.
