A trio of (oc­ca­sion­al­ly use­ful) tips for work­ing with mea­sure­ment fields to re­size and trans­form type, frames, and oth­er objects.

Resize, Move, and Transform by Percentage

Ever find your­self in need of cut­ting some­thing down to half, dou­bling the size of type, or blow­ing up an im­age frame 319.2678%? (No, I don’t think I’ve done the last one ei­ther, but you get the point.) In an ap­pli­ca­tion with god-like con­trol over po­si­tion­ing and siz­ing of ob­jects to the ten-thousandth of an inch, some­times you just want to use a per­cent­age. InDesign can do that, al­though it isn’t obvious.

Most mea­sure­ment fields in InDesign ac­cept percentage-based val­ues re­gard­less of the mea­sure­ment sys­tem dis­played. X and Y po­si­tion fields, Width and Height di­men­sions fields, col­umn and gut­ter width fields in Text Frame Options, the Stroke Weight field, and even the Character palette’s Font Size and Leading fields all ac­cept a per­cent­age as a val­ue. Double the size of your 10.25 pt type by sim­ply typ­ing 200% in­to the Font Size field. Move an ob­ject left by half it’s cur­rent po­si­tion by typ­ing 50% in­to the X co­or­di­nate field.

Note: Entering a per­cent­age like 120% in the Character palette’s Leading field does not set the lead­ing to 120% of the type size. It mul­ti­plies the cur­rent lead­ing val­ue by 120%; thus, 10 pt lead­ing be­comes 12 pt re­gard­less of whether the type size is 4 or 48 points. To make lead­ing rel­a­tive to the type size again, you must set Leading to Auto and ad­just the de­f­i­n­i­tion for Auto Leading in the Justification di­a­log on the Paragraph palette’s fly­out menu.

On the Fly Measurement System Conversions

Not on­ly can InDesign take per­cent­ages, but it can al­so take mea­sure­ments in any oth­er sys­tem it un­der­stands and con­vert them on the fly.

For in­stance, let’s say you’re work­ing in dec­i­mal inch­es (set in Preferences > Units & Increments) when your col­lab­o­ra­tor in Europe asks you to size an ob­ject to X mil­lime­ters wide. While you couldgo in­to the pref­er­ences and change your mea­sure­ment sys­tem tem­porar­i­ly, all your oth­er ob­jects’ po­si­tion­ing and siz­ing val­ues will be con­vert­ed to mil­lime­ters as well. You could al­so go to Google​.com and ask it to “con­vert X mm to inch­es” and bring the re­turned val­ue back to InDesign. Or, you could save your­self a trip and just let InDesign do the conversion.

Anywhere your cur­rent mea­sure­ment sys­tem pref­er­ence is revealed–for ex­am­ple, the Width, Height, X, and Y fields on the Transform palette–as well as most oth­er places InDesign han­dles measurement–Font Size, Leading, Stroke Weight, and so on–accepts mea­sure­ments in any sys­tem InDesign comprehends.

Perhaps you need to fit a one-line head­line in­to a 1.5-inch space. You could try to do that vi­su­al­ly, or you could sim­ply en­ter 1.5″ in­to the Font Size field on the Character palette. To sat­is­fy your European col­league, en­ter her val­ue fol­lowed by mm in­to the Width field on the Control palette. On the fly InDesign will both re­size the ob­ject and do the con­ver­sion back in­to dec­i­mal inches.

InDesign un­der­stands all of the fol­low­ing mea­sure­ment no­ta­tions ap­pend­ed to nu­mer­ic val­ues: Percentage (%), pi­cas (p), points (pt), inch­es (in, i, “), mil­lime­ters (mm), cen­time­ters (cm), and ci­ceros (c).

Spare the Calculator, Spoil the Designer

Now that you can do per­cent­ages and dif­fer­ent mea­sure­ments, it’s time for the coolest of the trio of mea­sure­ment field se­crets: Using InDesign as a vi­su­al calculator.

Let’s sup­pose you have an 8.5 x 11 page with .875-inch in­ner mar­gins and .415-inch out­er. What would be the width of a frame if the frame is sup­posed to be half the width of the live area? Beats me. I won’t even both­er fig­ur­ing it out be­cause InDesign can do it for me in a cou­ple of quick steps.

First, I’ll draw a rec­tan­gle from margin-to-margin. If I did it cor­rect­ly (Snap to Guides helps), the Control palette will re­veal the width of the rec­tan­gle, and thus my live area, as 7.21-inches wide. Instead of di­vid­ing that by two in my head (I get enough left-brain work­out bal­anc­ing my check­book), I’ll sim­ply ask InDesign to di­vide the frame’s width in half. In the Control or Transform palette Width field I’ll add /2 af­ter the 7.21 in it al­ready con­tains. I hit Enter/Return, my frame re­sizes, and I’m al­ready halfway to the swatch­es palette to set the color.

Most of InDesign’s mea­sure­ment fields can han­dle ba­sic math–addition (+), sub­trac­tion (-), mul­ti­pli­ca­tion (*), and di­vi­sion (/). Even bet­ter, it can do it with mixed mea­sure­ment sys­tems. For ex­am­ple, 4 in + 3p2 adds 3 pi­cas and 2 points to the four inch­es for an end re­sult of 4.5278-inches.

You may not use these mea­sure­ment field se­crets every day, but they do come in handy from time to time. They’re in InDesign for the same rea­son the Pen and Pencil tools were in­clud­ed: To save you trips to oth­er tools.
