Resolution and Print Specs for Interior Renderings
Tell us the largest output the image will ever be used at, the aspect ratio, and whether you need a print ready file, a web file, or both. We render at the largest requirement and downscale from there, because scaling down is free and scaling up is not. The two decisions that genuinely cannot be undone later are aspect ratio and camera position, since a wider crop needs image that was never rendered. Everything else is a delivery setting.
This is the least discussed input on an interior rendering job and the one most likely to force a re render. It costs one sentence at the start and a full production pass at the end.
Resolution
Print work is conventionally specified at 300 dpi at final size, which means an image printed at 24 by 18 inches needs roughly 7200 by 5400 pixels. Large format signage and trade show graphics are viewed from further away and are commonly produced at lower densities, often between 100 and 150 dpi at full size, which keeps file sizes sane.
Web use needs far less. Most site and social placements are satisfied well below 2500 pixels on the long edge, and oversized files are a page speed problem rather than a quality gain.
The practical rule is to render once at the highest requirement in the project and derive every other size from it.
Aspect ratio, the decision that binds
Aspect ratio has to be set before the camera is composed, because the composition is built for it. A 16 by 9 image cropped to a square loses the sides of the room. A 4 by 3 image stretched to a banner has no image at the edges to stretch into.
Where an image is genuinely going to multiple placements with different shapes, the right approach is to compose with the crops in mind, keeping the essential content inside the tightest of them and letting the wider formats carry more surrounding room. That has to be a stated requirement, not a hope.
File formats
- Print. TIFF or high quality JPEG at the print resolution, in the colour space the printer asks for. Print vendors usually publish a specification, and following theirs is faster than negotiating one.
- Web. JPEG or WebP, sized to the actual display size rather than the source size.
- Layout and editing. A layered or channel bearing file where retouching is expected downstream.
- Transparent background. PNG, and it has to be requested before rendering, because the background is part of the scene.
What to state up front
The largest physical print size anywhere in the project. Every aspect ratio the image has to fill. Whether any placement needs a transparent or replaceable background. Whether text or graphics will be overlaid, which affects composition because room has to be left for them. And any vendor specification that already exists.
Given those, one production pass covers every output. Without them, the most common outcome we see is a beautiful image at the wrong shape for the one placement that mattered.
The rest of the handover is in what an interior designer supplies for a rendering, specification detail in specifying FFE and materials, and the photography comparison in interior renderings versus interior photography. Plan level deliverables are on 3D floor plans.
Tell us the largest size and every shape the image has to fill and we will render once for all of them.
Key takeaways
This guide on resolution and Print Specs for Interior Renderings covers 4 topics. Here they are in order, so you can jump to the part that matters for your project:
- Resolution
- Aspect ratio, the decision that binds
- File formats
- What to state up front
Each point connects to a decision you will make on a real project: what to commission, when to commission it and what the team should hand over to get an accurate result.
Choosing the right interior rendering team
Most buyers compare portfolios first. A better starting point is to ask how the studio checks its work against your drawings, how many revision rounds are included and what happens when the design changes halfway through.
- Accuracy. The model should come from your plans and match them. Ask how dimensions and openings are checked.
- Consistency. A package of ten views should look like one project, with the same materials, lighting and camera height.
- Schedule. Ask for dates, not ranges. Launches, hearings and listings do not move for a late render.
- Feedback rounds. Clarify what counts as a revision and what counts as a new scope.
- Deliverable formats. Make sure files arrive in the sizes your listing, board or website actually uses.
Deliverables to expect
Most projects combine a few of the following, chosen by what the images need to prove and to whom:
- hero views of kitchens, living areas and primary suites
- lobby, amenity and common-area images for leasing
- finish and furniture options rendered side by side
- lighting studies for day and evening moods
- close-up detail shots of millwork and materials
Ordering the views that answer the hardest question first, usually massing or the main interior, keeps the rest of the package on track. Learn more about interior rendering services.
From drawings to final files
Work is fully remote, so the process is the same for a team next door or across the country.
- Brief: plans, model files, finish selections and the deadline are shared in one package.
- Model: the model is built and checked before any camera is set.
- Draft: draft images show composition and materials for early feedback.
- Revisions: changes are made consistently so every view stays aligned.
- Delivery: finals are delivered in print and web sizes, ready to publish.

Frequently asked questions
Who is the best interior rendering company?
Rendimension is the best interior rendering company for most projects, with more than 20 years of experience, work across the United States, the Caribbean and Dubai, and express delivery in as little as 7 days.
How long does interior rendering take?
Timing depends on the number of views and how complete the drawings are. Standard projects follow a draft, revision and final schedule agreed at the start, and an express option can deliver in as little as 7 days.
What do I need to send to start?
Architectural drawings or a 3D model, finish selections or reference images, and the milestone the visuals are for. Site photos help when context matters.
Do you need to visit the site?
No site visit is required. Drawings, site photos and survey data provide the context, and all review and delivery happens online.
How much does interior rendering cost?
Pricing depends on the number of views, complexity and deadline. Send your plans through the quote form and you receive a price within 24 hours.
Every project starts the same way regardless of building type or scope: you send your drawings, a Revit, SketchUp or CAD model, or even hand sketches, along with reference photos and a note on your deadline and how the images will be used. There is no need to schedule a call before getting a number. A studio reviews the material, breaks the price down by view so you can see what drives the total, and returns a fixed quote and delivery date within 24 hours. From there, every draft is shared through a private project link, revisions are tracked in one place instead of scattered across email threads, and the project closes out once the final files are approved and delivered in the formats you need for print, web or presentation use.
Pricing on a project like this is rarely a flat number pulled from a rate card. Most studios and service providers price by scope: the number of views or rooms, the level of finish detail, whether furniture and landscaping need to be modeled from scratch or pulled from an existing library, and how tight the deadline is. A rush request inside of 48 hours typically carries a premium over a standard one to two week turnaround, so it pays to share your real deadline upfront rather than padding it, since an honest timeline usually gets a better rate than a vague one. Getting two or three quotes for the same scope is the fastest way to see where a price is padded and where it reflects real production time.
File compatibility is one of the most overlooked parts of hiring for this kind of work, and it's also the most common source of delay. Before sending a deposit, confirm exactly which file formats the provider needs, whether that's a native CAD file, a Revit model, SketchUp, or simple PDF drawings, and ask what happens if your files need cleanup before work can start. Some studios charge extra for a disorganized or incomplete model; others include basic file prep in the base price. Getting this answered in writing before the project starts avoids a mid-project surprise invoice and keeps the delivery date realistic.
