For a 100-inch 16:9 screen, plan for the HL6810ATV’s lens to sit about 2.55–3.32 m (8.4–10.9 ft) from the screen. That range comes from Acer’s published 1.15–1.5 throw ratio; the projector’s body, cable bend radius and mounting hardware require additional depth. Acer gives a nominal example of 100 inches at 2.5 m, so the exact installation point depends on zoom position, lens shift and the regional specification.
The HL6810ATV is a conventional mid-throw projector, not an ultra-short-throw model. Its advertised image range is 30–300 inches on Acer’s current regional page, while the August 2023 user guide specifies 45–300 inches and a 1.5–7.6 m clear-focus distance. Check the manual for your market before designing around the smallest image size.
What room size does the Acer HL6810ATV need?
Room size is determined primarily by the distance from the projector lens to the screen, not by a single manufacturer-defined room dimension. For a 16:9 image, multiply the diagonal by approximately 0.8716 to obtain image width, then multiply that width by the HL6810ATV’s 1.15–1.5 throw ratio. The result is the usable lens-to-screen range.

These figures are planning calculations from Acer’s ratio, not an independent installation measurement. Leave extra space behind or above the lens for the projector chassis, power lead, HDMI or network cables and ventilation. A ceiling mount or shelf may place the lens several centimetres away from the projector’s rear edge, so measure from the lens position rather than from the wall or the back of the case.

| Screen diagonal | Approximate 16:9 image width | Lens-to-screen distance | Planning distance in feet |
|---|---|---|---|
| 80 in | 1.77 m (5.80 ft) | 2.03–2.65 m | 6.7–8.7 ft |
| 100 in | 2.21 m (7.26 ft) | 2.55–3.32 m | 8.4–10.9 ft |
| 120 in | 2.66 m (8.72 ft) | 3.05–3.98 m | 10.0–13.1 ft |
| 150 in | 3.32 m (10.89 ft) | 3.82–4.98 m | 12.5–16.3 ft |
For example, a room that is only about 3 m deep may accommodate an 80-inch image, but it is at the short end of the 100-inch range once projector depth and cable clearance are included. A room with roughly 4 m of clear optical distance can support a 120-inch image, although seating, wall width and ambient light still decide whether that size is practical.
Use the 100-inch reference correctly
Acer’s product information cites 100 inches at 2.5 m. Treat that as a nominal reference, not a promise that every unit will fill exactly 100 inches at exactly 2.500 m. The 1.15–1.5 ratio covers the full zoom range, and the optical measurement point is the lens. Regional specifications, zoom position and lens-shift settings can move the final image a little.
How much depth should you reserve?
Start with the calculated lens-to-screen distance, then add the projector’s physical depth and a service margin for cables. If the lens will be near the rear wall, a ceiling plate or shelf can consume part of that margin. Avoid pushing the projector against a wall or enclosing it tightly: the installation must preserve the manufacturer’s ventilation clearances for the chosen orientation.
Can the HL6810ATV project a 120-inch image?
Yes. A 120-inch 16:9 screen has an image width of about 2.66 m, producing a calculated lens-to-screen range of approximately 3.05–3.98 m (10.0–13.1 ft). Measure the room’s clear optical path at the intended zoom setting; a 3.1 m lens position uses the near end of the range, while almost 4 m uses the far end.
A 120-inch image is not automatically the best choice for a room that can technically fit it. The wall must be at least as wide as the image, the ceiling must allow the required vertical placement, and seating should not be so close that viewers see pixel structure or have to scan the image. Brightness also changes with screen size: the same light output is spread over a larger area, and uncontrolled daylight or room lighting has a greater effect on perceived contrast.

When 100 inches is the better fit
Choose 100 inches when the room has about 2.55–3.32 m of optical depth but limited wall width, when seating is relatively close, or when you cannot control ambient light. It provides more installation tolerance than a 120-inch image and leaves more options for a shelf, rear cable routing and a conventional ceiling mount.
When 150 inches is realistic
A 150-inch 16:9 image requires about 3.82–4.98 m from lens to screen and a wall roughly 3.32 m wide. That is a large-room installation. Confirm that the screen surface, seating distance and light control justify the size before buying a screen; the throw-ratio calculation only proves that the lens can form the image.
Is the Acer HL6810ATV short throw?
No. Acer’s 1.15–1.5 throw ratio places the HL6810ATV in a conventional mid-throw range. It is designed to sit several metres from a large screen, unlike an ultra-short-throw projector that forms a 100-inch image from a position close to the wall. Do not use ultra-short-throw furniture or assume that placing the HL6810ATV a few centimetres from the screen will work.
The projector does provide useful placement controls: manual 1.3x zoom, manual focus, 55–65% vertical lens shift and a 110% projection offset. Those controls make it easier to align the image within a room, but they do not change the fundamental throw-ratio range or turn the projector into a short-throw design.
Screen-size limits and the 30-inch versus 45-inch discrepancy
Acer’s current regional product page advertises a 30–300-inch image range. The original August 2023 user guide instead lists 45–300 inches and a clear-focus projection distance of 1.5–7.6 m. Both documents agree on the 300-inch upper limit, but they do not state the same lower limit.

| Acer HL6810ATV user guide | Original issue, August 2023 | 45–300 in | 1.5–7.6 m clear-focus projection distance |
Use the current Acer page for the advertised range in your region, but use 45 inches as the conservative minimum when a manual is the only document available. Before purchasing a very small screen, download the manual associated with your market and model identifier. A regional page or firmware package can differ from the document supplied for another market.
How to calculate your own throw distance
- Choose the diagonal. Decide whether you want an 80-, 100-, 120- or larger screen. Confirm that the wall and screen frame can accommodate its physical dimensions.
- Convert diagonal to image width. For a 16:9 screen, multiply the diagonal in inches by 0.8716, then convert inches to metres or feet. A 100-inch diagonal is about 2.21 m wide.
- Apply both ends of the throw ratio. Multiply width by 1.15 for the closest lens position and by 1.5 for the farthest. For 100 inches, 2.21 × 1.15 is about 2.55 m and 2.21 × 1.5 is about 3.32 m.
- Measure from the lens location. On a shelf, measure from the front lens position; on a ceiling mount, mark where the lens will sit, not where the mounting plate touches the ceiling.
- Add installation clearance. Reserve room for the chassis, ventilation, power and signal cables, and access to controls. If the resulting position is against a wall or in a walkway, reduce the screen size or reconsider the mounting location.
- Validate with the regional manual. Check the model’s stated focus distance, image-size limits, mounting orientation and any regional differences before drilling holes or ordering a fixed screen.
Placement controls and mounting options
Manual zoom and focus
The 1.3x manual zoom lets you fill a selected screen from different points within the 1.15–1.5 throw range. Manual focus means the final sharpness adjustment is made at the projector after it is mounted. Lock or secure a ceiling mount before focusing, because moving the projector after adjustment changes alignment.
Vertical lens shift
Acer specifies 55–65% vertical lens shift. Lens shift moves the image vertically without physically tilting the projector, which is preferable to excessive keystone correction because it preserves the intended image geometry. The percentage notation can vary by manufacturer, so use the on-screen adjustment and the regional installation diagram to determine the exact centreline limits for your unit.
Projection offset
The specified 110% offset describes the image’s vertical relationship to the lens when mounted in the supported orientation. It affects where a ceiling-mounted or shelf-mounted image lands relative to the lens. Plan the screen’s top or bottom edge using Acer’s mounting diagram rather than assuming that the lens is centred on the image.
Supported orientations
Acer lists front, front-ceiling, rear and rear-ceiling projection modes and supports ceiling mounting. Rear projection requires a suitable translucent screen and enough space behind it; it is not a substitute for the throw distance because the projector still needs the calculated optical path to the screen surface.

Acer announced the Vero HL6810ATV on May 22, 2024. Its launch information describes the 4K UHD output, 4,000 ANSI-lumen laser/LED hybrid source, Android TV dongle and up-to-30,000-hour ECO life. Acer also states that specifications, prices and availability vary by market, so do not assume that a specification or bundle listed in one country applies elsewhere.
Room-planning examples
Small media room: 80 inches
For an 80-inch screen, the lens should be about 2.03–2.65 m from the screen. This size is the most forgiving option when the room is shallow or when a rear wall, sofa or doorway limits the projector position. Measure the image width—about 1.77 m—before buying a fixed frame.
Typical lounge: 100 inches
The 100-inch case needs 2.55–3.32 m of lens-to-screen distance. A shelf at the rear of a 3.5 m room may work once projector depth and cable clearance are deducted, while a ceiling mount can place the lens farther forward. Use the zoom to fit the screen without relying on digital resizing.
Longer room: 120 inches
At 3.05–3.98 m, a 120-inch screen usually requires a dedicated long wall or a rear ceiling position. Check that the screen’s 2.66 m width leaves room for speakers, curtains and wall trim. If daylight enters from side windows, blackout curtains or a screen selected for the room’s light level may matter more than another increase in diagonal.

The lens range is approximately 3.82–4.98 m and the image width is about 3.32 m. This option needs careful structural planning for a ceiling mount, a wide screen wall and controlled lighting. The projector’s maximum advertised image size is 300 inches, but the 150-inch example is already large enough that seating distance and screen material should be evaluated before choosing the upper limit.

Installation checklist before buying
- Measure the uninterrupted lens-to-screen path, then compare it with the throw range for your chosen diagonal.
- Mark the screen’s actual image width and height, not only the diagonal.
- Allow for the projector body, mount or shelf, ventilation and cable bend radius.
- Confirm that the ceiling, shelf and wall can support the selected installation hardware.
- Check whether the vertical lens-shift range places the image at a comfortable height without tilting the projector.
- Verify front, rear, ceiling and rear-ceiling orientation requirements in the regional manual.
- Plan power, HDMI and network routes before fixing the mount; avoid tight bends and inaccessible connectors.
- Decide whether Standard or ECO brightness better suits the room, remembering that Acer’s quoted 3,200-lumen ECO figure and 30,000-hour life apply to ECO operation.
- Confirm the screen’s aspect ratio is 16:9 if you are using the calculations in this guide.
- Check local price, warranty, included Android TV dongle and availability because Acer says these vary by market.
Common mistakes and how to avoid them
Measuring from the back of the projector
Throw ratio is measured from the lens to the screen. Measuring from the rear panel can make the available room appear longer than it is and leave no room for cables. Mark the lens centre or front optical position when laying out the installation.
Treating 2.5 m as the only 100-inch distance
The 2.5 m figure is Acer’s nominal 100-inch example. The published ratio allows approximately 2.55–3.32 m across the zoom range. Use the range when deciding whether a shelf or mount will fit.
Assuming lens shift eliminates all alignment limits
Lens shift increases placement flexibility but has a finite vertical range. It cannot move the projector arbitrarily sideways or replace the need for a level mount. Keep the projector square to the screen and use the documented shift range first.

Using a 4:3 calculation for a 16:9 screen
The distances in this guide use a 16:9 image width. A different aspect ratio changes image width for the same diagonal, so recalculate if you plan a non-16:9 screen.
Buying a screen before checking the local specification
The 30-inch minimum on a current regional page conflicts with the 45-inch minimum in the August 2023 guide. Verify the document for your market before ordering an unusually small screen or assuming a close-focus installation.
Buying verdict
The HL6810ATV is a strong fit for buyers who can place a projector roughly 2.55–3.32 m from a 100-inch screen, want 4K UHD output and high rated brightness, and value manual zoom, vertical lens shift, ceiling support and an included Android TV dongle. A 120-inch image is feasible with about 3.05–3.98 m of lens-to-screen depth; 150 inches needs a substantially larger room.
It is the wrong geometry for a near-wall installation. Treat it as a mid-throw projector, verify the 30- versus 45-inch lower-limit discrepancy against your regional manual, and design around the lens position rather than the projector’s rear edge. Acer’s prices, specifications and availability vary by region, so confirm the local product page and warranty before placing an order.
