PlanSnapper vs Xactimate for Square Footage Measurement
Xactimate is the industry-standard platform for property insurance claims — used by adjusters to scope repairs and estimate replacement costs. PlanSnapper is a GLA calculator designed for appraisers, real estate agents, and investors. Both involve square footage, but they serve entirely different purposes.
What Xactimate does
Xactimate (made by Verisk) is a claims estimation and scoping tool used by insurance adjusters, public adjusters, and restoration contractors. It includes a sketch tool for drawing room layouts, a massive database of repair line items with current local pricing, and integration with insurance carrier workflows.
Xactimate's sketch module measures in interior dimensions — room by room — and calculates wall surface area, floor area, and ceiling area to drive line-item repair quantities. It is specifically designed for scoping fire, water, wind, and other damage repairs for insurance claims.
What PlanSnapper does
PlanSnapper calculates ANSI-compliant Gross Living Area (GLA) from existing floor plans. You upload a floor plan image or PDF, trace the exterior perimeter, set a scale using one known wall length, and get appraisal-standard square footage. It follows ANSI Z765-2021 methodology — the same standard used in residential appraisals for Fannie Mae and FHA loans.
The core difference: methodology
The measurement standards are fundamentally different:
- Xactimate uses interior dimensions. Adjusters measure rooms from wall-to-wall inside. This produces useful repair quantities (flooring, drywall, paint) but does not match appraisal GLA.
- PlanSnapper uses exterior dimensions (ANSI Z765). Appraisers measure the exterior footprint of above-grade living area. Exterior measurement produces GLA — the number used in appraisals, listings, and property records.
- Interior square footage runs roughly 5–10% less than exterior for the same space, because wall thickness is excluded.
This means Xactimate's numbers and PlanSnapper's numbers will not match — and should not be expected to. They're measuring different things for different purposes.
Side-by-side comparison
| Feature | Xactimate | PlanSnapper |
|---|---|---|
| Primary user | Insurance adjusters, contractors | Appraisers, agents, investors |
| Measurement method | Interior room dimensions | Exterior perimeter (ANSI Z765) |
| Standard | Insurance claims (Xactware) | ANSI Z765-2021 / Fannie Mae |
| Input | Draw room-by-room | Upload existing floor plan |
| Output | Repair scope + cost estimate | GLA by level (PDF) |
| Use case | Scope damage for claim payment | Calculate listing/appraisal GLA |
| Multi-story | Yes | Yes |
| Cost | $200–$300+/mo (subscription) | $9 day pass or $29/mo |
| Learning curve | Steep (training required) | Under 5 minutes |
Do they overlap?
Some professionals need both. An insurance adjuster who also needs to report the GLA to a carrier for a total-loss replacement cost calculation might use Xactimate for the repair scope and PlanSnapper (or an appraisal) to confirm above-grade GLA.
In practice, the tools are used in different parts of the real estate workflow. Xactimate is the post-loss claims tool. PlanSnapper is a pre-sale, appraisal, and listing tool.
Which one do you need?
Use Xactimate if: you are scoping repair costs for an insurance claim, working in restoration or remediation, or producing a Xactimate estimate for an adjuster or carrier.
Use PlanSnapper if: you need ANSI-compliant GLA from a floor plan for a residential appraisal, a listing, a buyer's due diligence review, or a lender-conforming report.
