Frequently Asked Questions
Everything below answers the questions that come up most often about how NGFINITY works, what you can compare, and how your data is stored.
1. Is NGFINITY free to use?
Yes. Every feature currently available on NGFINITY can be used without creating an account or paying a subscription fee.
2. Do I need an account to create a comparison?
No. You can start building a comparison right away, with nothing to register or sign in to.
3. Can I compare more than two things at once?
Yes. You can add as many people, animals, public figures, or other entities as you like and display them together in a single lineup.
4. What is included in the Entity category?
Entity covers Mountains, including peaks such as Mount Everest and K2; Objects, including everyday items from basketball hoops to wind turbines; and Astronomical Objects, including planets, stars, black holes, galaxies, nebulae, comets, and the observable universe. Because of the scale involved, most Entity comparisons are easiest to read after zooming out.
5. Can I generate an image using AI instead of uploading one?
Yes. Inside Custom Image, switch to Create AI Image, describe the subject in the prompt field, set a name and height, and select Generate & Add AI Model.
6. Does the color outline change an entity's height?
No. A color outline is a visual label only. It makes a character easier to pick out in a crowded lineup and has no effect on the height or position of the entity itself.
7. How do I find a specific public figure or character?
Open the Celebrity category and use the search bar to look up a name directly instead of scrolling through the full list. Results filter as you type, so you only need to enter a few characters of the name you are looking for.
8. What does the Clear All button do?
Clear All removes every entity currently on the canvas so you can start a new comparison without reloading the page. A confirmation dialog appears first so you cannot lose a lineup by accident.
9. Can I change an entity's position without clearing the whole canvas?
Yes. There are two ways. Open the Lineup Order panel and click the up or down arrow next to a figure to move it, or press and hold a figure directly on the canvas and drag it left or right to reposition it in the lineup. Both methods leave the rest of the comparison untouched.
10. Can I edit a figure's name or height after adding it?
Yes, for custom figures added through Add Person, Custom Image Upload, or AI Image Generation. Open the Lineup Order panel and click the label underneath the figure; a small editor appears where you can change the name and height, and the figure resizes automatically to match.
11. Does NGFINITY support US measurements?
Yes. Heights can be entered in feet and inches, and NGFINITY converts the value into the metric system used for the underlying scale. The unit toggle also updates the ruler and every figure's height label across the canvas.
12. Are the mountain and astronomical measurements exact?
They are close approximations intended for visualization. Real-world mountain elevations vary by sea-level baseline, and several astronomical values represent scientific estimates rather than fixed figures.
13. How accurate are the prehistoric animal sizes?
Prehistoric animals are shown using predefined dimensions based on commonly cited estimates. Actual sizes are difficult to determine with certainty from fossil evidence alone, so these entries should be treated as reasonable visual approximations rather than confirmed measurements.
14. What can I change in the Customize panel?
The Customize panel controls the appearance of the canvas rather than the comparison data itself. You can switch the grid style between Lines, Clean, and None, set a custom color for the measurement marks, and choose a Light, Dark, Ocean, or Sky background for the canvas.
15. Will changing the grid color or background affect the height values?
No. Grid style, grid color, and background themes are purely visual. They change how the canvas looks, not the measurements or scale of anything you have added.
16. Is there a limit to how many entities I can add?
There is no fixed limit built into the tool itself. Very large lineups can become harder to read on smaller screens, so it is worth using the Lineup Order panel or the horizontal scrollbar to keep things organized as a comparison grows.
17. Does zooming affect the height values, or just the view?
Zooming only changes the view. Zoom In and Zoom Out scale how the canvas is displayed, including with a press-and-hold option for continuous zooming, without altering the actual height of anything you have added. The ruler and every figure's label update together so the numbers on screen always match the visual scale.
18. Is NGFINITY usable on a phone or tablet?
Yes. The layout, zoom controls, and Customize panel are all designed to work across desktop, tablet, and mobile screens, and the 3D view automatically adjusts its quality and controls for touch devices.
19. Can NGFINITY be used for classroom or educational purposes?
Yes. The visual, hands-on format works well for classroom demonstrations, presentations, and personal research into relative size, alongside its everyday use for casual comparisons.
20. Are the height calculator and unit converter part of the same tool?
They are separate, standalone pages linked from the same navigation bar, intended for quick numeric lookups rather than the full visual, side-by-side comparisons built on the main canvas.
21. Can I search within the Animal or Entity categories the same way as Celebrity?
Yes. Add Person aside, every browsable category — Celebrity, Animal, and Entity — includes its own search bar that filters results as you type.
22. Does NGFINITY store or reuse my uploaded image?
No. An uploaded image is used only to build the comparison you create with it, and it is stored locally in your own browser so the chart survives a refresh. NGFINITY does not use the image for any other purpose, does not use it to identify you, and does not send it to external servers.
23. How do I switch between 2D and 3D view?
A 2D / 3D toggle sits above the canvas, next to the unit toggle. Select 3D to open the three-dimensional view, or 2D to return to the flat lineup. Your chart stays exactly as it was in either mode, and any entity you add in 2D shows up in 3D automatically.
24. What can I do in the 3D view?
The 3D view lets you inspect your lineup from any angle. In Free mode you can orbit, pinch, or scroll to move the camera around the scene, and in 1st Person or 3rd Back mode you can walk, run, and jump around the figures as if you were standing beside them. Both modes keep a floating name and height label on every figure, and the ruler beside the lineup rescales itself automatically to match the tallest entity on screen.
25. What are the controls in 3D play mode?
On desktop, use W, A, S, and D to walk, Shift to run, Space to jump, and the mouse to look around. On mobile, the on-screen D-pad in the bottom-left moves, dragging anywhere on the canvas looks around, and the JUMP button above the D-pad handles jumping. A dropdown at the top-left lets you choose which figure to play as, and the controls box in the corner can be collapsed if you want a clearer view of the scene.
26. Can I change the 3D camera sensitivity or D-pad size?
Yes. The gear button in the 3D view opens a settings panel with sliders for look sensitivity, movement speed, D-pad size, and the horizontal and vertical offset of the on-screen D-pad. Your preferences are saved on your device and reapplied the next time you open the 3D view.
27. Does the 3D view work on mobile?
Yes. The 3D view is built to work on phones and tablets as well as desktop. It automatically lowers the geometry detail and pixel ratio on mobile devices to keep the frame rate smooth, and it swaps the keyboard controls for an on-screen D-pad and dedicated jump and action buttons. A rotate button in the top-right switches the 3D display into landscape for a wider view.
28. Does switching to 3D change my chart or height values?
No. The 2D and 3D views share the same underlying chart, so switching between them does not add, remove, or rescale anything. Figures keep the same heights, names, and colours in both views, and any edit you make in one is reflected in the other.
29. What are the block tools in the 3D view?
The 3D view includes a small building system. Three tools sit in the toolbar at the bottom of the screen: a stone block for placing 1-metre cubes, a pickaxe for breaking them, and a bare hand for a simple punch animation. On desktop, switch between them with the 1, 2, and 0 or Q keys, and use the tool with F — hold it with the pickaxe equipped to mine through a block. On mobile, tap the toolbar buttons and use the HIT button above the D-pad. Blocks you place are saved and restored the next time you open the page, and the jump height is tuned so a figure can clear exactly one block but never two stacked.
30. Can I share my chart with someone else?
Yes. The Share button above the ruler opens a dialog that generates a link containing your entire lineup — every figure, its height, colour, name, position, and the current zoom level and unit system. Anyone who opens the link sees your exact chart on their own device and can keep editing it from there. The link can be copied to your clipboard or shared through your device's native share sheet. Uploaded photos are excluded from the link because they are stored locally in your browser, but every other figure appears normally.
31. What is the beacon I sometimes see in the distance in 3D?
The beacon is a landmark that marks the position of your lineup from anywhere in the 3D scene. It combines a slowly rotating crystal, a soft glow that is rendered through terrain, and a tall faint light shaft that is visible from a long distance. If you ever wander far from your figures in first-person mode, look for the glow to find your way back.
32. Is my lineup saved automatically?
Yes. NGFINITY saves your lineup, zoom level, unit preference, grid style, grid colour, background theme, site theme, and — in 3D — every block you have placed and the tool you were last holding. When you come back to the page, everything is restored automatically. Opening a shared link takes priority over your local save, so a link from someone else always loads their chart instead of your own.
