LGT FLC INADVERTENTLY FLEW THROUGH TFR DURING A DAYLIGHT VFR FERRY FLT DUE TO NOT KNOWING THE EXACT RADIUS AND ALTITUDE OF THE TFR.

Narrative

THE INCURSION TOOK PLACE ON A FLT FROM ZZZ1 TO ZZZ2. I HAD RECEIVED A WX BRIEFING AND FILED A VFR FLT PLAN WITH ZZZ3 FSS. AFTER DEPARTING ZZZ1 I ALTERED MY DIRECT COURSE TO THE WEST TO AVOID ZZZ4 AIRSPACE AND ZZZ5 CLASS B. I WAS CRUISING AT 4500 FT MSL BELIEVING THAT I WAS CLR OF ALL AIRSPACE TO THE W OF ZZZ5 INCLUDING THE TFR (W AND ABOVE). SHORTLY AFTER THE INCURSION AREA APPROX 1 HR AND 15 MINS INTO THE FLT; I CONTACTED ZZZ6 APCH FOR FLT FOLLOWING ABOVE ZZZ6 AIRSPACE STILL AT 4500 FT MSL. I THEN CONTINUED TO LAND AT ZZZ2 AND CLRED CUSTOMS. AFTER CLRING CUSTOMS; I STARTED TO RELOCATE THE ACFT ON THE FIELD; I WAS ADVISED BY ZZZ2 GND TO CONTACT ZZZ5 TRACON AND A NUMBER WAS GIVEN TO ME. I CONTACTED THEM IMMEDIATELY. TO MY SURPRISE; THE TRACON MANAGER TOLD ME THAT I FLEW THROUGH THE MIDDLE OF ZZZ7 TFR. I WAS AWARE OF THE EXISTENCE OF THE TFR (THERE ARE THREE IN THE AREA). I MADE TWO FALSE ASSUMPTIONS; FIRST I THOUGHT THAT THE TFR WAS TO 3000 FT SIMILAR ARE THE TWO OTHER TFR'S; AND THUS GIVING ME 1500 FT OF CLRNC; IN REALITY I WAS 500 FT BELOW THE 5000 FT TOP LIMIT. I ALSO THOUGHT THAT THE RADIUS WAS 2.5 MILES NOT FIVE; AGAIN SIMILAR TO THE TWO OTHERS CLOSE BY. POSSIBLE CAUSES AND PREVENTION: TFR'S INCONSISTENCIES; IN A GENERAL REGION WHERE GEOGRAPHIC ALLOW WHY NOT MAKE TFR'S MORE CONSISTENTLY THE SAME SIZE; SUCH AS WITH CLASS D AIRSPACE (ATA). THIS WOULD MAKE IT EASIER THAN WORKING WITH DIFFERENT SIZED AIRSPACES IN SUCH A CLOSE PROXIMITY. BETTER PUBLICATION OR COMMUNICATIONS; AS LONG AS THE TFR'S ARE IN EFFECT AND THEY ARE NOT ON THE CHARTS THE BRIEFER (FSS) SHOULD REINFORCE THE EXISTENCE AND SIZE OF THE TFR WITHOUT QUERY.
