Screen size chart? Viewing distance vs screen size.

[DCUK6]

Hi,

 

Does anyone know of a sizing chart for a smart board/interactive display in classrooms?

 

We got a fairly long room and trying to work out if we should go for 65" or 70"+.

 

Have drawn on the wall but its hard to tell.

 

edit. Got a idea. Going to take a projector into the room

How do you mean? In terms of positioning the projector in the room?

 

I tend to use Projector Point to get a pretty good idea: Projector Point

IMO if you go for an interactive display you can go slightly smaller than an IWB because of the enhanced clarity.

 

I would go for 70" for most classrooms if you were replacing a 77" smartboard. Also consider that you are likley swapping a 4:3 screen for a 16:9 screen. Width will be very similar but not as high.

 

As Ric_ says "bigger is better" but once you get above 70" the cost skyrockets. Theres not much difference in cost between 65" and 70" really.

 

If you really need bigger than 70" a projector is still your only real option.

Thanks,

 

We originally had a quote for a 70" display and fitting for £2590 as it was on clearance.

 

Finance took so long to approve the order that this deal went.

 

Now looking at £3100 but thatsgoing to take awhole new writeup. 65" is £2899 and can go ahead immediately.
