Best Camper Van Conversion Planners Compared (2026): VanSpace 3D, Plan Your Van, PlanMyCamper & VanLogic
Reading time: approx. 9 minutes
Before you drill the first hole, you make a decision that shapes the entire build: which tool do you plan with? That choice matters more than most people expect at the start — from the rough floor plan all the way to the final vehicle inspection.
The market for camper planning software has grown a lot over the last few years, but the tools differ fundamentally in what they can actually do. This comparison puts the four best-known options side by side, honestly — based on real feature differences, not marketing claims.
The four tools at a glance
| VanSpace 3D | Plan Your Van | PlanMyCamper | VanLogic | |
|---|---|---|---|---|
| Layout planning | 2D + 3D | 2D | Configurator | 2D + 3D |
| Automatic weight calculation from material | No | No | No (manual entry) | Yes |
| Axle load & centre of gravity, live | No | No | Axle load only (calculator) | Yes, both |
| Collision check against real vehicle structure | No | No | No | Yes |
| Multiple build methods for self-built furniture | No | No | No | Yes |
| PDF inspection report | No | No | Partial (weight sheet) | Yes |
| Languages | English | multilingual | German | 8 languages |
| Real smartphone app | No (desktop download only) | No (browser only) | No (browser only) | Yes (iOS & Android) |
VanSpace 3D
VanSpace 3D is the strongest pure layout tool in this comparison: over 500 furniture and accessory items, 15+ vehicle chassis brands, and a first-person view that lets you feel tight spots and walkways before you ever pick up a saw. For pure spatial planning and visualisation, it’s very well made.
What’s completely missing: any form of weight, axle load, or centre of gravity calculation. You plan purely visually — whether the finished build is even roadworthy or legally registrable, you only find out once you’ve built it and weighed it.
Plan Your Van
A simple, free entry point for 2D floor plans — often the first recommendation in van life blogs for people just getting started. It’s straightforward to use, and the free tier is enough for a rough overview.
No 3D, no weight calculation, no check against the real vehicle structure. Good for early idea-gathering, not for technical planning.
PlanMyCamper
A free, German-language platform with its own weight calculator for payload and axle load — honest and useful for a rough estimate. The difference to VanLogic: the weight of each component is estimated and entered manually, not calculated automatically from shape, dimensions, and material. Move a piece of furniture, and you have to recalculate it yourself.
No 3D, no centre of gravity or tipping risk value, no collision check against wheel arches, roof taper, or sliding doors.
VanLogic — the difference in detail
VanLogic isn’t a pure drawing tool and it isn’t a pure calculator — it’s both, permanently linked together. Every change to your layout immediately affects weight, axle load, and centre of gravity — not only once you recalculate it by hand.
Real vehicle dimensions and real vehicle structure
The vehicle database covers all common base vehicles (Ducato/Jumper/Boxer, Sprinter, Crafter/TGE, Transit, T5/T6, and many more) with real-world dimensions. Wheel arches, roof taper, and sliding doors exist as genuine geometric structure in the layout — not just as reference lines. Furniture that collides with this structure is flagged before you build it.
Multiple build methods for your self-built furniture
Self-built furniture isn’t just defined by shape and size, but by its actual construction method: solid, box with lid, box without lid, open frame, closed frame, panel, or an angled box for sloped roof sections. Each build method has its own weight formula based on the real construction — a hollow box weighs like a hollow box in the app, not like a solid block.
Automatic weight calculation — never manual
The weight of every object comes from its shape, dimensions, material, and build method. You never type in an estimated kilogram figure — that’s the central difference to all three other tools in this comparison.
Axle load, centre of gravity, and tipping risk, live
As you plan, you see the current front/rear axle load distribution, the centre of gravity, and a warning for critical tipping risk in real time. Move a piece of furniture, and everything updates instantly.
A 3D preview of your build
Your plan can be viewed as a 3D model directly in the app — already available in the app stores today. (Additional 3D features such as an X-ray mode and an exploded view for assemblies are fully built and coming in an upcoming update.)
An inspection report as PDF
Generate a PDF report with all technical data, axle loads, and tank scenarios (full/empty) at the tap of a button — ready to show at the inspection.
Fully usable on mobile
VanSpace 3D is a desktop-only download for Windows and Mac, while Plan Your Van and PlanMyCamper run in the browser only. Of these four options, VanLogic is the only one with a real native app for iOS and Android — you can measure, plan, and move furniture right at the vehicle, no laptop and no internet connection required.
8 languages, works offline
No account, no internet connection required — your entire plan stays local on your device, available in German, English, French, Italian, Spanish, Dutch, Polish, and Portuguese.
Coming next
These features are already fully built and will ship in an upcoming update:
- Build templates — complete, ready-made layouts for different vehicle sizes to load and adjust directly
- Assembly template library — pre-built furniture assemblies (kitchen blocks, beds, bathroom areas) to drop in
- Sandbox mode — try every Pro feature for as long as you like, no purchase required
- 3D X-ray view — see through furniture to check hollow spaces and shelves
- 3D exploded view — pull an assembly apart into its individual pieces
- Extended hollow-cavity collision detection — also works with rotated, round, and L-shaped self-built furniture
Conclusion: which tool fits you?
If pure visualisation with a huge furniture library matters most to you and weight isn’t a concern, VanSpace 3D is a good choice. For a quick, free first sketch of your ideas, Plan Your Van is enough. If you just want an independent weight calculator without planning the full layout, PlanMyCamper is a solid option.
If you want to treat layout, vehicle structure, build method, and weight as what they actually are — one connected system, not separate steps — VanLogic is currently the only tool that brings all of that together in one app.
