Part 1. What is Render Resolution, Pixel Density, DPI, LPI, and PPI

When it comes to creating 3D rendering images, understanding the technical terms that affect the clarity of the 3D rendering is essential. The resolution, pixel density, PPI, DPI, and LPI are all important concepts you might be confused about:

Resolution refers to the number of pixels in an image. The higher the resolution, the more pixels there are, and the sharper the image will appear.

DPI, on the other hand, typically refers to the number of dots per inch in a printed image.

PPI specifically refers to the number of pixels per inch when an image is printed. While LPI, or lines per inch, is another term sometimes used in printing to describe the number of lines of dots that can be printed in one inch.

If the 3D architecture animation is for online viewing, for example, integrated onto the realtor’s official site for a virtual room tour, a render resolution of 720p (1280*720 px) or 1080p (1920*1080 px) is suitable. But if the animation is intended for theatrical release, a bidding auction, for example, a higher resolution like 2k (2048*1080 px) or 4K (4096*2160 px) is recommended for achieving the detail level and quality you are expecting.

Best Resolution for 3D Animation:

Animation for Online Viewing: 1280*720 px or 1920*1080 px;
Animation for Theatrical Release: 2048*1080 px or 4096*2160 px;

Note: While these recommended render resolution covers most cases when it comes to choosing the right resolution if you are printing for a specific use that is not listed above, it is highly recommended that you contact the printing studio beforehand to learn all the parameter requirements and make sure your intended use of the renders are conveyed to the 3D artists clearly before the rendering starts. In that way, the 3D artists are able to render your project with the quality and schedule you are expecting.

Part 6. Communicate With The 3D Artists Before The Project Starts

It can be tricky to choose a resolution smartly on different usage scenarios, so are there any practical tips to communicate with the 3D artists effectively when outsourcing your 3D Archviz project? Sure, to eliminate misunderstanding and ensure a smoother workflow, it is essential to get ready a project brief to establish clear and effective communication with the 3D archviz studio, leading to a successful 3D rendering project:

1. Clearly define your project requirements: Before you begin working with a 3D artist on your project, make sure you have a clear understanding of your project requirements. This includes details such as the viewing angles, the amount of the render, the object or scene you want to render, the level of detail you require, and the desired output format and resolution.

Note: Tell your project manager the intended use of your 3D render, for web or for printing material. The experienced 3D visualization studio will know what resolution you are expecting. If you have a specific requirement on the size and resolution for the extremely large display purpose, tell them before the project starts for time-saving, money-saving, and a smoother workflow.

2. Provide reference images and materials: If there are any specific styles or aesthetics you are looking for, tell your project manager. Providing reference images or materials can help the 3D artist understand the look and feel you’re going for. You can also provide sketches or concept art to help convey your ideas more clearly.

3. Set clear deadlines: Set a clear deadline for the project and make sure they are communicated clearly to the 3D artist. Be realistic about the timeline and factor in time for revisions and adjustments.

4. Give feedback and be specific: Provide feedback to the 3D artist throughout the project and be specific about what you like and don’t like. And include all comments in one feedback sheet to avoid missing and causing a longer turnaround time. This will help them adjust their work to better meet your needs and expectations time-effectively.

For a render resolution of a full-width website image, usually used as a homepage banner or page background, it needs at least 2560 px in width to make sure the images look sharp. And for other digital use of images, like the portfolio, blog, social media platform, and more, you will get the best practical size to scale down to and compress the image without quality loss before uploading. You don’t want your website to full of stunning projects but load super slow to get them fully displayed, do you?

One free image-compressing software I used the most is called: Riot. You can also use others like Compress2go, TinyPNG, etc. Compressing images before uploading them to your website makes a great difference to save space for more images.

Best Resolution for The Web:

Pixel Density: 72PPI;
Image Size: At Least 2560 px for full-width website images; Edit and scale down for social media platforms;
Bonus Tip: Compressing the image before uploading keeps the image quality while down-scale the file size by like 80%.

3. How to Pick The Best Resolution for Printing Material
When it comes to the render resolution of the printing material, there are multiple factors you need to consider beforehand: Printing process, printing size, and viewing distance.

3.1. Printing Process: The ideal resolution also depends on how the material is printed. Printing from a digital printer requires lower resolution than a traditional offset printer.
3.2. Printing Size: The golden rule for choosing the best resolution for printing material is: The bigger the size of the canvas, the lower the DPI.
3.3. Viewing Distance: If the print will be viewed from a distance, a lower resolution is enough, however, if the print will be viewed up close, a higher resolution is required.

In most cases, a resolution of 300dpi is adequate for most print jobs: For any canvas that’s up to 5ft² in size, such as flyers, business cards, brochures, catalogs, and small banners. And the optimal pick of the resolution in pixels is 3-4k in width.

For larger banners and posters that are 5-10ft² in size, you can lower the resolution to 150dpi for great print quality while lower the price. But if your poster will be viewed up close, such as in a gallery or a trade show, you should use a higher resolution. A resolution of 300-600 dpi is usually sufficient for most poster sizes.

And for those larger than 10ft² in size, you can choose 20-75 dpi accordingly. For instance, if you are printing for a billboard showcase that is viewed from 30ft² away, you can use 20-30 dpi for the printing.

Best Practical Printing Resolution:

For business cards, fryers, brochures, catalogs, and small banners: 300 dpi and 3-4k in width;
For posters: 150 dpi;
For billboards: 20-75 dpi;

4. How to Pick The Best Resolution for Animation
The resolution requirements of an animation are different from that for a still image: Target platform and audience are the key factors to consider.

If the 3D architecture animation is for online viewing, for example, integrated onto the realtor’s official site for a virtual room tour, a render resolution of 720p (1280*720 px) or 1080p (1920*1080 px) is suitable. But if the animation is intended for theatrical release, a bidding auction, for example, a higher resolution like 2k (2048*1080 px) or 4K (4096*2160 px) is recommended for achieving the detail level and quality you are expecting.

Best Resolution for 3D Animation:

Animation for Online Viewing: 1280*720 px or 1920*1080 px;
Animation for Theatrical Release: 2048*1080 px or 4096*2160 px;

Note: While these recommended render resolution covers most cases when it comes to choosing the right resolution if you are printing for a specific use that is not listed above, it is highly recommended that you contact the printing studio beforehand to learn all the parameter requirements and make sure your intended use of the renders are conveyed to the 3D artists clearly before the rendering starts.
