Can we have actual PCB size printed onto the layout of every PCB we see posted on this Forum?

I donīt know what to say,for all APEX projects i have printed as "Actuall size" and havent any troubles yet. That was with HV23,NX14 (16),APEX PROTECT+CLIP PSU,APEX PSU7,APEX AX12...

Anyway here are some dimensions that i have found at forums here in Serbia and at diyaudio.com:
APEX 550w class B PCB size 110x105mm
APEX A75 LM3886pcb PCB size 53x25mm
APEX AX12 size 47,5x82,5mm
APEX AX14 PCB size 60x82,5mm
APEX B200 tda 7294 stereo/bridge PCB size 115x62,5mm
APEX B500 Component 220x52,5mm
APEX D14 PCB size62,5x82,5mm
APEX G100 bas guitar PCB size 260x95mm
APEX H900 PSU PSU PCB size 105x70mm
APEX HV23 PCB size 200 x 50mm
APEX HV350 PCB 200x50mm
APEX NX14 pcblayout NX14 pcb size 82,5x60mm
APEX ML3 Mic volume Tone Preamp PCB size 100x40mm
APEX Protect and Clip PSU PCB size 90x130mm
APEX PSU5 pcb 140x90mm
APEX PSU7 PCB PCB size 200x75mm
APEX A-class Shunt Regulator PCB 80x77.5mm
APEX X1 sub PCB size 60x50mm

That is all i have of written dimensions. When i come in that dilema,i usually take a measure of IC,relays or transistors components at jpg. and than adjust width and height of pcb if needed. My first print is usually at everyday printing paper so i can compare ic/transistor/relay pinout directly with layout just to be sure. Hope i helped at least a little bit...

Thatīs what I would expect from the wise DIYer. As I usually say, to the good listener, half a word is enough!
