TOP, RIGHT or LEFT ALIGNEDFORM LABELS?

28

Top Aligned Labels

• When data beingcollected is familiar

• Minimize time tocompletion

• Require more verticalspace

• Spacing or contrast isvital to enableefficient scanning

• Flexibility forlocalization andcomplex inputs

29

Top-aligned Labels

eBay Express

30

Right Aligned Labels

• Clear associationbetween label andfield

• Requires less verticalspace

• More difficult to justscan labels due toleft rag

• Fast completiontimes

31

Right-aligned labels

Basecamp, 37Signals

32

Left Aligned Labels

• When data required isunfamiliar

• Enables labelscanning

• Less clear associationbetween label andfield

• Requires less verticalspace

• Changing label lengthmay impair layout

33

Left-aligned labels

Ad Connections

34

Eye-tracking Data

• July 2006 study by MatteoPenzo

• Left-aligned labels• Easily associated labels with

the proper input fields• Excessive distances between

labels inputs forced users totake more time

• Right-aligned labels• Reduced overall number of

fixations by nearly half• Form completion times were

cut nearly in half• Top-aligned labels

• Permitted users to captureboth labels & inputs with asingle eye movement’

• Fastest completion times

35

• For reducedcompletion times &familiar data input: topaligned

• When vertical screenspace is a constraint:right aligned

• For unfamiliar, oradvanced data entry:left aligned

BEST PRACTICE

36

USER• Provide Information:

want to register,make a purchase,etc.

• Finish Quickly:no one likes filling informs

DESIGNER• Maximize completion

rates• Gather known data:

name, address,credit card

• Use a minimumamount of verticalscreen real estate

CONSIDER: RIGHT-ALIGNED LABELS
