Scaling 1/8" to 1 inch in Adobe Illustrator

[Dilly_Dally]

I feel SO stupid that I can't understand this.  (I am an engineer for pete's sake!)  

I have a sewing pattern which is drawn to scale where 1/8" = 1".

I want to scale it up to print it.  I have tried several things with the % which is available but it just doesn't seem to work!  I have googled and searched this forum, but am not getting enough information to do exactly what I want.

If 1/8 = 100% and 1" = 8 X 1/8 than the scale factor is 8 x 100 = 800%

I tried that....musta done something wrong....way too big.

You can also do this, create 2 rectangles. One 1 inch and one 1/8 inch

Position them with a corner aligned.

Turn on Smart Guides

Select the small one.

Select the Scale Tool

Click on the common corner to set the transformation point and drag until the opposite corners meet.

Alt/Option Click somewhere outside to see the scale percentage.

Dilly Dally,

Are you perhaps getting the size 1/0.24 (approximately 4.1667) times too big?

If that is the case, you may somehow get a 300 PPI resolution into things, maybe in connexion with an image.

But I believe it would help helpers to see some screenshots.

Unknown to most, it is quite easy to directly show images in posts, hence the following general suggestion:

Please show images by using the Insert Photos button (looks like moon over mountains) for each at the top of the reply box which makes everything appear right there in your post together with your text, rather than he more conspicuous Drag&drop attachment which requires helpers to open a new tab for each image and wait for its showing, then go back and forth; and if they just click it and wait for its showing and press the X to get back to the text, the image is gone so they have to open it again and wait to see it again.
