Not sure why I'm worried about it but the size difference between this version and the last posted is about 10:1... It bothers me when programs start to bloat so rapidly.

The connection to this website sucks big time.
In two attempts it takes more than a minute to download only 2 MB.

I included offline help files and all the dlls that the program needs in the portable version, causing the bloat - sorry.

The non-portable installer version only installs files not found on the host - large download, but much smaller footprint if you have a newish OS.

It's cool man, was just curious more than anything. Tried deleting everything but the ruler.exe, but it wouldn't run then.

Couldn't find a way to contact you on the website for this program, I was wondering if there was a way to resize the ruler without the mouse. I work from a laptop and prefer not to use the mouse if I can avoid it. Touchpads are being as finiky as they are. Any chance I might get a copy of the previous source to play around with, for my personal use only, not for distribution.

try deleting all but these files: Ruler.exe, dummy.html, license.txt, params.res, DBRTL100.BPL, RTL100.BPL, VCL100.BPL, VCLDB100.BPL, CC3270MT.DLL, BORLNDMM.DLL. You can del the help dir as well (if you have an internet connection, F1 takes you to the website). Were you thinking of something like this: Alt+Left Arrow resizes left, Alt + Up resizes top...when the ruler has focus? if so, give me a couple of days...

Any chance of a "Stay On Top" option so the ruler isn't lost behind graphics that we're editing? Thanks!

ap 2009-11-21 14:51

I prefer PMeter that is tiny and have more features, e.g. in On-screen Ruler if you put centimeters, no have relation with the reality, in PMeter you can adjust the paremeter dpi, so the centimeters adjust to a true ruler put on your screen

JK 2009-11-21 15:41

@ mecha: F5 toggles "Stay on top"...see https://sites.google.com/site/rulerhelp/shortcuts-1
@ap: I will provide adjustable dpi in the next version.

A very useful program for Web developers, but I prefer the ruler in the also portable PicPick (http://www.portablefreeware.com/index.php?id=1496) program.

It hogged completely my 1.8 GHz CPU, at 99%, making the app unresponsive, requiring forced termination. (My system: xp home, sp2)

Plus, every time the app is started it request an outbound connection, up to three times, when blocked (Remote Address: vhost.phx7.nearlyfreespeach.net HTTP (TCP: 80); also: .phx8 and .phx10.)

@ap: Thank you for your recommendation of PMeter. It's the ruler I was looking for!

JK 2009-12-21 17:38


try disabling the check for update at startup option to disable the outbound connection. it is for the version check.


Toxic 2009-12-22 20:42

Written in bloatware Delphi, has no graceful way to exit, redrawing bugs on resizing. 6 MB for a such poor functionality? Hell no!

jkic47123 2009-12-23 01:25

@toxic - try hitting esc to close the program when it has focus.

dianoga 2009-12-25 05:50

Horrible update. Version 1.x was heaps better and only required a single file. Even if you disable automatic update at startup, this new 2.1 version still insists on calling home on each run of the program. If you deny it in your firewall it will hang! Looking for another ruler now.

jk 2010-01-02 18:09

@dianoga: i will look into why it is calling home when auto update is disabled - can't immediately figure it out. the next version will be a single file, much smaller - i forgot to set compiler flags to do this the last time.

PeterM 2010-03-21 23:20

Yes, program should be reduced in size, though to 2 files: the EXE and an INI file. At present I don't see much advantage
over JR Screen ruler which I use and is a 160K sized exe.

Dan 2010-04-24 17:24

Great update. Simple with a lot of utility that the other rulers lack - thanks

webbie1 2010-05-13 16:51

Love it - fast, uncluttered, easy to use and maneuver

tauf 2010-09-27 13:45

I hadbeen looking for this kind of solution for ages when I stumbled upon this prog. It really makes me feel like working on a "true" desktop with long table and a straight edge.

boogoo 2011-02-10 08:28

@ap: Pmeter is just what I was looking for: a portable pixel ruler and color picker in one. @jk try simplifying the options box, maybe remove the upper banner?

Nicamati 2014-05-14 18:01

Thanks JK. Great ruler for preparing basic scale drawings in MS Word etc. for DIY projects. I especially like the calibration facility, as I prefer to draw at a size that fits the screen space rather than be constrained to a fixed ruler measurement, so this is perfect for that. (Looked at PMeter, but it didn't seem to suit my purpose at all; nor did various others that were either too limited, irritating or had time limits.) :-)

Hi - I've been looking for a successor to the legendary Cool Ruler from FabSoft, which won't run on W7. Really, I need something that sits horizontally and vertically, measures in pixels, mouse/touchpad grab and move, AND allows me to put as many custom marks as I need.

Is this possible?

It's the last bit which is so frustrating. I've found ONE only which allows me to put ONE custom mark. I am getting quite frustrated that so many authors think I need all kinds of fancy goodies--but if I want a protractor or set-square, I will search one out! And it better have custom marks :[

I don't need colour pickers, magnifiers, diagonal placement, skins & etc. Even the "stay on top" is not truly necessary.
