How to Become an Interior Designer in 2026
Quick answer: Becoming an interior designer usually takes about 2 to 4 years of education. You complete an associate or bachelor’s degree (programs typically cost $6,000 to $25,000), build a strong portfolio, gain experience through internships or assistant roles, and can earn the optional NCIDQ Certified Interior Designer credential from CIDQ. Certification is voluntary in many states but required in some that regulate the title. The median interior designer salary is $67,190 per year ($32.31/hour), and employers post about 7,800 openings nationwide each year (BLS, May 2025).
Interior designers use color, lighting, materials, and furniture to make spaces both functional and visually appealing. They work on homes, offices, hotels, retail stores, and more, shaping how people experience the rooms they spend time in.
How to Become an Interior Designer
Most interior designers enter the field after about two to four years of education, depending on the degree level they choose. There is no single national license, though some states regulate the title and require certification. You build the career through education, a strong portfolio, hands-on experience, and an optional professional credential.
1. Earn a High School Diploma or GED
A high school diploma or GED is the starting point for nearly every interior design program. Before you enroll, build the skills the work depends on. Art and drawing classes develop your eye for proportion, color, and composition. Math, especially geometry, helps with scale drawings and space planning, while basic physics and building-science topics make later coursework on lighting and materials easier to follow. Computer-design or drafting electives are valuable because professional interior design runs on software, so any early exposure to tools like AutoCAD or SketchUp gives you a head start. Get comfortable with general computer and presentation software too, since you will spend a lot of time building mood boards, renderings, and client presentations. If you are changing careers and already hold a diploma or another degree, you can move straight to choosing a program. Many strong designers come from unrelated fields and bring useful skills in communication, budgeting, and project management.
2. Complete an Interior Design Program
This is the core of your training. An associate degree takes about two years and can lead to entry-level or assistant roles, while a bachelor's degree takes about four years and is the most common route into professional design positions. When comparing schools, look for accreditation by the Council for Interior Design Accreditation (CIDA), which reviews programs against recognized curriculum and faculty standards that many employers value. Typical coursework covers design fundamentals and color theory, space planning, computer-aided design and 3D modeling, lighting, textiles and materials, building codes, and accessibility standards. Many programs also build in studio projects so you graduate with real work to show. A growing number of certificate and degree programs are available online or in hybrid formats, which lets working students learn at a flexible pace. Whatever format you choose, confirm the program's accreditation before you enroll, since a CIDA-accredited degree also helps if you later pursue NCIDQ certification.
3. Build a Strong Portfolio
In interior design, your portfolio often matters as much as your degree. Employers and clients want to see what you can actually produce, so collect your best work as you go. Save studio projects, floor plans, mood boards, 3D renderings, and any real or volunteer projects you complete. Show range by including different room types and styles, and show technical skill by including CAD drawings and detailed material selections alongside finished visuals. If you have not had paid work yet, design concepts for friends, redesign a room in your own home, or take on small volunteer projects for community spaces to fill out the portfolio. Present it cleanly, both as a polished PDF and as a simple website, since hiring managers frequently review portfolios online. A well-organized portfolio that explains your design thinking, not just the final look, is one of the strongest ways to stand out in a competitive field.
4. Gain Work Experience
Coursework and a portfolio open the door, but real experience is what builds a career. Look for an internship while you are still in school, since many programs help place students with design firms, architecture offices, or furniture and staging companies. After graduation, entry-level and assistant designer roles let you practice the parts of the job that school cannot fully teach: coordinating with contractors and vendors, sourcing furniture and finishes within a budget, managing timelines, and working directly with clients. Pay attention to how senior designers handle client expectations and project changes, because client management is a major part of the work. Each project also gives you new pieces for your portfolio and references for future jobs. Over time, this experience is what qualifies you for the work hours that the NCIDQ certification requires and for more senior positions.
5. Consider NCIDQ Certification
The most recognized credential in the field is the NCIDQ Certified Interior Designer certification, issued by the National Council for Interior Design Qualification (NCIDQ / CIDQ). In many states it is voluntary, but some states that regulate the interior design title or practice require it, so check your state's rules early. To qualify, you generally need a combination of interior design education and documented professional experience, then you pass the NCIDQ examination, which tests areas like building codes, construction standards, and professional practice. Even where it is optional, the credential signals expertise and can support higher pay and senior roles. Joining a professional association such as the American Society of Interior Designers (ASID) is also worth considering, since associations offer continuing education, networking, and job leads. Together, certification and a professional network help you move from entry-level work into established designer and leadership positions.
