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

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. The collision check also recognises hollow cavities in self-built furniture — a hollow cabinet that only overlaps a wheel arch on the outside while leaving it fully clear on the inside is correctly treated as collision-free, even for rotated, round, or L-shaped objects.

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, frame with thin panelling, 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.

The deepest self-build system on the market

Other tools either offer a furniture library to drag in (VanSpace 3D, Plan Your Van) or no self-build system at all. VanSpace 3D does allow free building from basic geometric shapes like cubes, cylinders, or planes — but with no connection to material or weight. In VanLogic, the self-build system itself is the basis for the weight calculation: eight build methods (solid, box with/without lid, open/closed frame, frame with thin panelling, panel, angled box), freely selectable material with its own density for the carcass, panelling, shelves, and fronts, additional drawers and doors that each affect the weight, and multi-part assemblies that you can freely combine and save as your own reusable template. Every one of these choices immediately affects the calculated weight — not just the look.

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.

3D preview with X-ray view and exploded view

Your plan can be viewed as a 3D model directly in the app — including an X-ray mode that makes furniture transparent so you can check hollow spaces and shelves, and an exploded view that pulls multi-part assemblies apart into their individual pieces so you can follow how they’re built.

Ready-made templates instead of starting from zero

If you don’t want to start completely from scratch, you can fall back on complete build templates for different vehicle sizes and adjust them directly, or drop in individual pre-built furniture assemblies (kitchen blocks, beds, bathroom areas) from a library. Your own assemblies can also be saved as a reusable template.

Test every feature without limits

In sandbox mode, you can try every Pro feature for as long as you like, with no obligation to buy — your plan there is deliberately not saved permanently, so you only decide once you know the app is right for your build.

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.

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.
