What is the difference between PlanSnapper and Coohom?

PlanSnapper is a browser-based tool for calculating ANSI-compliant GLA from existing floor plan images and PDFs. Coohom 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 Coohom?

It depends on your workflow. PlanSnapper focuses on GLA calculation from floor plans — uploading an image, tracing the perimeter, and getting square footage. If Coohom 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 Coohom?

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 Coohom offers equivalent GLA functionality depends on its feature set.

How much does PlanSnapper cost compared to Coohom?

PlanSnapper and Coohom 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 Coohom?

Ease of use depends on your starting point. PlanSnapper tends to fit one type of user or workflow, while Coohom 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 Coohom 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 Coohom are most useful for creating sketches from scratch or capturing measurements in the field.

Which works better for calculating GLA — PlanSnapper or Coohom?

Both PlanSnapper and Coohom 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 Coohom handle existing floor plan PDFs?

Neither PlanSnapper nor Coohom 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 Coohom?

PlanSnapper and Coohom 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 Coohom: Which Tool Is Right for Floor Plan Work?

Coohom and PlanSnapper both work with floor plans, but they solve completely different problems. Coohom is a 3D design and visualization platform used by interior designers and furniture retailers. PlanSnapper is a measurement tool built for appraisers who need ANSI Z765-compliant GLA from an existing floor plan. Here is how they compare.

The short version

Coohom: A 3D interior design platform used by designers, retailers, and homeowners to visualize spaces and create rendered room layouts. You draw or import a floor plan, furnish it, and produce photo-realistic renders. Not designed for measurement or appraisal compliance.
PlanSnapper: A floor plan measurement tool built specifically for residential appraisers. Upload any floor plan PDF or image, trace the perimeter, set a known wall length, and get ANSI Z765-compliant GLA with above/below grade separation — without drawing anything from scratch.

PlanSnapper vs Coohom: at a glance

	PlanSnapper	Coohom
Primary use case	Floor plan measurement and ANSI GLA calculation	3D interior design and visualization
Upload existing floor plan	Yes — core workflow (PDF or image)	Yes — as a background trace reference
ANSI Z765 GLA calculation	Yes (above/below grade, compliant output)	No — measures rooms for design, not appraisal
Multi-story / above vs. below grade	Yes (each floor tracked separately)	Multi-floor supported for design, not GLA compliance
Appraisal-ready PDF report	Yes (address, GLA summary, labeled floor plan)	No
3D rendering	No	Yes — photo-realistic renders
Furniture / materials library	No	Yes — extensive product catalog
Works with CubiCasa / iGUIDE exports	Yes (optimized for these formats)	Partially (can import DXF; not purpose-built)
Price	$9 day pass / $29/mo	Free tier + paid plans (designer pricing varies)

Where Coohom wins

Coohom is an impressive platform for what it does. If you need to show a client what a room will look like after a renovation, create marketing visuals for a listing, or plan furniture placement in a new home, Coohom's 3D rendering engine is genuinely powerful. It has a large catalog of real furniture products from brands and manufacturers, making it useful for retail showrooms and interior design presentations.

For real estate agents who want to present a property visually — staged layouts, renovation concepts — Coohom provides tools PlanSnapper does not offer.

Where Coohom falls short for appraisers

No ANSI Z765 compliance. Coohom does not understand gross living area, above-grade vs. below-grade space, or ANSI Z765 calculation standards. Room dimensions in Coohom are for design accuracy, not appraisal compliance. You cannot produce a defensible GLA from a Coohom file.
No measurement-first workflow. Coohom is designed around drawing and designing from scratch. If you already have a floor plan from a CubiCasa or Matterport scan and just need to measure it, Coohom's full design stack is overkill — and you still would not get an ANSI-compliant output.
No appraisal report output. Coohom produces design presentations and renders. PlanSnapper produces a PDF report formatted for appraisal documentation — property address, per-floor GLA breakdown, labeled floor plan.
Steep learning curve for a measurement task. Coohom has a full 3D design workflow. Using it just to get a square footage number is like using AutoCAD to draw a rectangle — technically possible, but not what the tool is for.

Who should use Coohom

Coohom is the right tool for interior designers, design-build firms, furniture retailers, and real estate agents who need to create 3D visualizations of spaces. If your goal is showing clients what a space will look like — furnished, lit, rendered — Coohom is built for that.

Who should use PlanSnapper

PlanSnapper is built for residential appraisers and real estate professionals who need to calculate ANSI Z765-compliant GLA from an existing floor plan quickly and accurately. Upload the PDF or image, trace the perimeter, set one known wall length, and get a documented, compliant GLA output in minutes. No design workflow, no learning curve — just the measurement output appraisers need.

Already have the floor plan?

Upload any floor plan PDF or image and calculate ANSI Z765-compliant GLA in minutes. Works with CubiCasa, Matterport, iGUIDE exports, and any floor plan image.
