PlanSnapper vs Magicplan: Best for Appraiser GLA?

Magicplan and PlanSnapper both help real estate appraisers get to an accurate GLA, but they approach it from opposite ends of the workflow. Magicplan starts in the field, capturing a floor plan from scratch. PlanSnapper starts at your desk, measuring from a floor plan you already have.

How Magicplan works

Magicplan uses your smartphone's camera and AR to help you sketch a floor plan room by room. You point the camera at each corner and tap to place walls. The app assembles the rooms into a complete floor plan, which you can export as a PDF, JPG, or DXF.

For appraisers, Magicplan's main appeal is speed on-site. It is faster than drawing on paper and produces a clean digital plan you can annotate. However, calculating ANSI GLA still requires you to interpret the exported plan and apply ANSI rules manually (or use a separate tool).

How PlanSnapper works

PlanSnapper is a web-based GLA calculator. You upload a floor plan image or PDF: from any source. Set the scale using a known dimension on the plan, and trace the perimeter of each area. PlanSnapper calculates total square footage in real time and lets you designate areas as above-grade or below-grade for ANSI-compliant GLA.

PlanSnapper does not capture floor plans, but it works with plans from Magicplan, CubiCasa, iGUIDE, builder packages, county records, or photos of hand sketches. If a floor plan exists, PlanSnapper can measure it.

The appraisal workflow gap Magicplan leaves

Magicplan gives you a floor plan. It does not automatically give you ANSI GLA. You still need to identify which areas qualify as above-grade living space under ANSI Z765, exclude garages, stairwells, and below-grade rooms, and sum the correct areas. For appraisers who do this in their head or with a calculator, that is error-prone and non-defensible.

PlanSnapper closes this gap. After exporting your Magicplan floor plan, upload it to PlanSnapper, trace each area, tag it, and let the tool calculate the ANSI-correct GLA. It turns the Magicplan sketch into a traceable, auditable square footage figure.

When you might use both

Magicplan for field capture, PlanSnapper for GLA calculation. This is a common workflow for appraisers who want a fast on-site sketch but need a precise, documented GLA at the desk. The Magicplan PDF becomes the source of truth; PlanSnapper becomes the measurement layer on top of it.
