Clearing Guide Display Columns
These column sizes are for ads not covered in the regular sizes above. Small fractional ads do not usually have bleed and should be supplied to their booked depth in millimetres x their column measurement (a 10×2 ad would therefore be 100mm high and 92mm wide)
Clearing Guide Classified Columns
Classified advertising for Observer Magazine is type area only, without bleed. Ad sizes are given as height in cm x width in columns. Depth is usually converted to millimetres for delivery, so: a 10×2 ad would be 100mm (10cm) high and 63 millimetres (2 columns) wide. This measurement method applies to all advertising that doesn’t have bleed.
