About DesignCalc Pro

DesignCalc Pro was created for one reason: interior design projects fail because of preventable math mistakes. Paint is bought in the wrong quantities. Flooring is ordered with insufficient waste factored in. Furniture arrives and crowds the room. Light fixtures are placed too far apart or too close together.

What We Offer

We have built 35+ professional design calculators covering every stage of a residential interior project — from initial space planning and material estimation through furniture layout, lighting design, and color selection. Every tool gives you actionable numbers, not vague estimates.

Expert Guidance

Our articles are written by practicing interior designers and architects who understand both the theory and the on-site realities of design work. We cover design principles, material selection, project management, and the technical details that make the difference between a room that looks like a magazine spread and one that looks like it was assembled from a catalog.

Why We Exist

Good interior design should be accessible to everyone — not just clients who can afford a full-service design firm. DesignCalc Pro gives homeowners and independent designers the same calculation tools that professionals use, completely free. We believe that knowing how much paint you need, how to space your furniture, and how to plan your lighting layout are skills anyone can learn.
