RAM (random-access memory) is important for ensuring that your laptop can run multiple applications smoothly without crashing. For interior design, we recommend at least 16GB of RAM. If you're planning on using 3D modeling or rendering software, you may want to consider even more RAM. Also consider how much storage memory your laptop has. Interior design software can create large files, so you'll need a laptop with plenty of storage space. We'd recommend at least 512GB of SSD storage, but if you can afford it, 1TB or more is even better.
