# How to adjust corner rounding with varying sizes of shapes to be consistent?

How do you describe the relationship of a rounded corner to the dimensions of a shape? I want to create a rule of how much to round corners on our boxes, but want it to be applicable to varying sizes of boxes--but I am not sure how the math works. I would like all our boxes to look consistent no matter what the size. Thanks.

Under Object, there is Corner Option. In the Corner Option, you can control the size of the corner and the shape that you require. As for the shape, there is only 6 default corners to choose.

What if you made an item for each basic shape (square, tall rectangle, wide rectangle) and set the corner size on all of them. Then, if you need a larger version, just scale it. The proportions of the corner to the size of the objects will stay the same.

@brianst – I'm not exactly sure about what you want exactly…

A formula that shows the exact radius for the rounded corner in dependency of the scale factor of the object?

Object is scaled to 70%, radius now after the scaling should be: original radius * 1/0.7 ? (Result: 1.42857142857143) Something like this?

I don't think in indesign to adjust corner need to be so complicate. All you need to do is this

@teoszuchia123 – it depends how the scaling is done.

See the two options for scaling in the General Preferences for InDesign.

To make it more clear:

It happen if you are using transform. If you want to the corner to be consistent in any shape like rectangle or square even weird shape it is the must use corner option to determine the size of the corner.

In InDesign there is no option scaling a rectangle without scaling the effective radii of the corners.

So you have always ro adjust the radii. If using "Apply To Content", it's easier, just punch in the original values.

If using "Adjust Scaling Percentage" you have to do a small calculation.

And if you do a non-uniform scaling and want the radii stay intact, you have to:
1. Use the Path Menu: Open Path

2. Close Path

And moving the path points of the rounded corners according to calculated values from x and y scaling.

Hm. Wouldn't that a cool feature request? Scaling without losing the shape and radii of the rounded corners?

I think I'm missing the point here, but how is a 3x5 rectangle with a .5" rounded corner different from the same object scaled to 50%?

• ###### 10. Re: How to adjust corner rounding with varying sizes of shapes to be consistent?

Of course, the OP, brianst, could have changed the shape of the object without scaling. Then the radii of the rounded corners would have stayed intact.

As you might know, InDesign is able to do small calculations in the entry fields for values.

So to adjust the shape of the rectangle of my example to an effective size of 70% one could have used the width and the height field and punch in *.7 after the current values to retain the radii.

@Migintosh – the effective radii are shrinking to the scaled percentage while scaling.

Adjusting the form of the object, which is not scaling, will retain the radii.

Here the case for changing shape vs. scaling:

• ###### 13. Re: How to adjust corner rounding with varying sizes of shapes to be consistent?

Yes, but couldn't you make a sheet of rectangles with fixed proportions (like 1 to 1, 1 to 2, 2 to 1, etc.) and set a desired corner radius on all of them to the same amount? Then, if you need a 2 to 3 object, just copy it and scale it to the size you need. I think that would look reasonable. I don't think it needs to be this complicated.

Of course, but what to do, if the damage is already done?
Calculations… ;-)

It's even better to put them into the objects pane, for quick access. Just my two cents...

@brainst – are you still with us?
(15 answers and no comment from the OP…)

Thanks all for the replies. I think just creating the objects in one format and scaling them for use, will likely be our easiest fix.
