Screen size calculator

This is a little project for a client. It isn't finished yet but it does work.

Does it make sense? Is it simple to understand what to do?

Diagonal "AA" in or "BB" in doesn't make sense to me. Should the second "in" be cm / mm? and if so the numbers don't make sense.

Other than that it looks very easy to use and quite intuitive.

I’m not seeing that error. Yes the second column should be mm. That’s what I see when inches is selected as the units.

What selections did you make?

It seems straight forward. The only thing that could be an issue is that first link isn't https, which on my browser comes up with a big warning. Basically, a 'here be dragons' sort of thing, so that might make them a bit wary.

Hi @fisicx,

I think it worth clarifying that you have to put an entry into one of the sizing for the "magic to happen" - I clicked on the different screen types and was expecting the size to be filled in?

Once I worked it out, it all looks fine.

That's not my calculator so don't care about https. TBH I think both the alternatives are a bit clunky.

Good point. I'll change the labels.

The problem with prefilling is there are a bazillion different screen sizes. Whatever I choose as the default would be wrong!

General comments:

• Your design is more modern!
• Inches/mm - choose mm and the unit stays in inches next to the entry boxes.
• Screens tend to be measured in CM, not mm (inches officially dies with tubes, but us...... mature consumers still use it!). However, if t is for projectors, it is a bit different.

When switching from inch to mm the figures don't change.

As screen sizes are usually specced on the diagonal would "Size (diagonal) to better and the first option? Or is it to determine what screen size they need for the space

Thanks Paul and &Marlon.

I’ll fix the units switching bug (it was me fiddling).

Client wants mm. But easily changed.

Agree about putting diagonals top. Will fix this.

Updates done.

There are some minor rounding issues when switching between units but I'll get these sorted (I'm only calculating to 3DP. Probably needs 6+).

The fact that when the aspect ratio is already chosen, you only need to enter one dimension out of height, width, and diagonal should be explained. A note something to the effect "only enter one dimension and the other dimensions will be calculated" added in small letters below "Enter screen size", I think would do that.

Also, since the diagonal is nearly always quoted in inches, then a separate units choice box for diagonal would be helpful so that the user could enter the diagonal in inches and a dimension in mm.

 

[fisicx]

Apologies for the delay in replying. I agree that some explanation may be needed but the calculator will be used on a B2B site used by those in the know so we can adjust after some focused user testing.

Not quite sure what you mean by "enter the diagonal in inches and a dimension in mm". When you enter any dimension the rest get updated along with the equivalent in the other units. I did experiment with 6 input fields (3 imperial and 3 metric) but it looked more clunky than the current iteration.

Nice work, very slick and to answer your original question, yes it's easy to understand what to do.

This is probably not something your client would care about or more importantly want to pay for you to address but I'm quite OCD and this is one of my bugbears...

...I always struggle with decimal inches and if I was measuring a space or screen with a ruler I wouldn't know what 0.125 of an inch is but I immediately understand 1/8 of an inch. So in my perfect world a calculator would include radio buttons allowing you to choose between decimal or fractional inches; technically more difficult to implement of course but it would be pretty cool for obsessives like me.

 

[fisicx]

Not that difficult to do. I’ll talk to the client.

As an aside. I know the US is determined to keep imperial measurements, as decimal is impossible to understand - but - using inches with a decimal point after it, is sort of decimal. I get a measurement of 1 and 11/18 but 1.237" just makes my brain squirm. In fact, the 1.237 sort of makes perfect sense and works on a calculator, but the fractions so common do not? I just explode when the engineering videos I watch on youtube, mix metric and imperial

 

[fisicx]

The problem here is screen sizes are almost always given in inches across the diagonal but width and height in millimetres or centimetres.

When I was mending helicopters for a living everything was metric but we used 1/8 or 3/16 rivets.
