What is the difference between PlanSnapper and Plnar?

PlanSnapper is a browser-based tool for calculating ANSI-compliant GLA from existing floor plan images and PDFs. Plnar is a separate tool with different core functionality. The right choice depends on whether you need to measure from a floor plan or perform a different task.

Can PlanSnapper replace Plnar?

It depends on your workflow. PlanSnapper focuses on GLA calculation from floor plans — uploading an image, tracing the perimeter, and getting square footage. If Plnar serves a different purpose in your process, the two tools may complement each other rather than compete.

Which is better for ANSI Z765 GLA calculation — PlanSnapper or Plnar?

PlanSnapper is purpose-built for ANSI-compliant GLA calculation from floor plan images. It handles PDF uploads, perimeter tracing, and automatic area calculation in a browser with no install required. Whether Plnar offers equivalent GLA functionality depends on its feature set.

How much does PlanSnapper cost compared to Plnar?

PlanSnapper and Plnar have different pricing models — one may charge per user, per project, or via annual subscription, while the other may offer a free tier or pay-per-use option. Check the comparison table above for current pricing details and which offers better value for your volume of work.

Which is easier to use — PlanSnapper or Plnar?

Ease of use depends on your starting point. PlanSnapper tends to fit one type of user or workflow, while Plnar is designed for another. If you are working from an existing floor plan PDF and need to calculate square footage quickly, a browser-based tool like PlanSnapper may reduce the learning curve entirely — no software installation required.

Do I need PlanSnapper or Plnar if I already have a floor plan PDF?

If you already have a floor plan as a PDF or image, you may not need either tool. PlanSnapper lets you upload the PDF directly and trace walls in your browser to calculate GLA — no software installation required. Both PlanSnapper and Plnar are most useful for creating sketches from scratch or capturing measurements in the field.

Which works better for calculating GLA — PlanSnapper or Plnar?

Both PlanSnapper and Plnar can support GLA calculation, but the workflow differs. One may require field measurement and sketch entry while the other may allow importing existing floor plans. If your starting point is an existing PDF or image floor plan, PlanSnapper provides a faster path — upload, trace, and get the GLA figure without entering either tool's workflow.

How do PlanSnapper and Plnar handle existing floor plan PDFs?

Neither PlanSnapper nor Plnar is primarily designed to import and calculate square footage from an existing PDF floor plan. Both tools are built around creating or capturing floor plans from scratch. If you already have a PDF floor plan, PlanSnapper lets you upload it directly, trace the walls, and get an accurate GLA figure without redrawing anything.

Which is better for occasional users — PlanSnapper or Plnar?

PlanSnapper and Plnar are both specialized tools with learning curves that reward regular use. Occasional users often find dedicated subscription tools hard to justify. For someone who needs to calculate square footage a few times a month, PlanSnapper is designed for exactly that — no training required, no annual contract, upload and measure in minutes.

PlanSnapper vs PLNAR: Floor Plan Measurement Compared

PLNAR and PlanSnapper both produce floor plan measurements, but they start from different points. PLNAR uses augmented reality on your phone to scan and capture a space while you are physically inside it. PlanSnapper works from an existing floor plan image — a PDF export, a CubiCasa scan, a Matterport floor plan, or a photo of a paper sketch — and calculates ANSI-compliant GLA in your browser. Here is how they compare.

The short version

PLNAR: A mobile AR scanning app that captures room dimensions while you walk through a property. Good for insurance adjusters, contractors, and home product companies who need to create floor plans from scratch on-site. Requires physical access to the property and an iOS or Android device. Pricing starts at $9.99/user/month for unlimited Snapshot projects; 3D projects billed separately by square footage.
PlanSnapper: A browser-based tool for measuring an existing floor plan image to calculate ANSI Z765-compliant GLA. If you already have a floor plan — from a scanning service, an MLS listing, an architect, or a previous visit — you do not need to scan again. Upload, trace the perimeter, set one wall length, and get your number. $9 day pass or $29/month unlimited.

PlanSnapper vs PLNAR: at a glance

	PlanSnapper	PLNAR
Primary use case	GLA calculation from an existing floor plan image	AR-based floor plan capture on-site
Requires property access	No — works from any floor plan image	Yes — must be physically present to scan
Device required	Any desktop or laptop browser	iOS or Android smartphone with AR capability
Input	PDF, image, CubiCasa/Matterport/iGUIDE export	Live camera scan of physical space
ANSI Z765 compliance	Yes — measures exterior perimeter GLA	Not the primary focus — measures interior dimensions
Best for	Appraisers, agents, investors verifying GLA from a floor plan	Insurance adjusters, contractors, home product sales teams
Pricing	$9 day pass · $29/month unlimited	$9.99/user/month · 3D projects billed by sq ft
Desktop app or install	None — runs in your browser	Mobile app required

When PLNAR makes sense

PLNAR is designed for capturing space dimensions when no floor plan already exists. If you are an insurance adjuster documenting a damaged property, a contractor measuring a kitchen for a remodel estimate, or a flooring company quoting a job on-site, PLNAR is a fast way to walk a space and produce a dimensioned floor plan without a tape measure.

It is also useful when you need to produce a floor plan from scratch and do not have access to a professional scanning service like CubiCasa or Matterport. You walk the property, PLNAR captures the room shapes using AR, and you get a floor plan you can share or annotate.

When PlanSnapper makes sense

PlanSnapper is for people who already have a floor plan and need a number. That is most real estate appraisers, most agents reviewing an existing listing, and most investors cross-checking county records. You received a CubiCasa scan from the listing agent. You downloaded the Matterport floor plan from the MLS. You have the architect drawings. You do not need to go back to the property — you need to measure what you have.

PlanSnapper also applies ANSI Z765-2021 methodology: you trace the exterior perimeter walls (not interior dimensions), set one scale reference wall, and get above-grade GLA. Basement and garage space is calculated separately. This is exactly what appraisers need for URAR reporting and Fannie Mae compliance.

Can you use them together?

Yes, in some workflows. If you use PLNAR to capture a floor plan on-site and export it as an image, you can then open that image in PlanSnapper to calculate ANSI-compliant GLA from the exterior perimeter. PLNAR generates the floor plan; PlanSnapper measures it. That said, most appraisers find it faster to use a professional scanning service (CubiCasa, iGUIDE, Matterport) or their own sketch and go straight to PlanSnapper from there.

The bottom line

PLNAR and PlanSnapper solve adjacent but different problems. PLNAR captures dimensions — you need to be at the property. PlanSnapper measures from an image — you need to have the floor plan. If you are a residential appraiser or real estate professional who regularly receives floor plans from scanning services or MLS listings, PlanSnapper gets you to ANSI-compliant GLA without ever opening a mobile app.
